A package may run git as part of its build process, and if the package
source code is not from a git checkout, then git may traverse up the
directory tree to find buildroot's repository directory (.git).
For instance, Poetry Core, a Python build backend, will read the
contents of .gitignore for paths to exclude when creating a Python
package. If it finds buildroot's .gitignore file, then Poetry Core will
exclude all of the package's files[1].
This exports GIT_CEILING_DIRECTORIES for both package and host builds so
that git will not traverse beyond $(BUILD_DIR)/$(BUILD_DIR_HOST).

This reduces open coding and allows to easily add a knob to enable
it treewide, where chosen packages can still opt-out via "no-lto".
Some packages used LTO, but not the linker plugin. This unifies 'em
all to attempt to produce better code.
Quoting man gcc(1):
"This improves the quality of optimization by exposing more code to the
link-time optimizer."
Also use -flto=auto instead of -flto=jobserver, as it's not guaranteed
that every buildsystem uses +$(MAKE) correctly.

Note: libnl, mbedtls and opkg only used the CFLAGS part without the
LDFLAGS counterpart. That doesn't help at all if the goal is to produce
smaller binaries. I consider that an accident, and this fixes it.
Note: there are also packages using only the LDFLAGS part. I didn't
touch those, as gc might have been disabled via CFLAGS intentionally.

PKG_BUILD_FLAGS is a new variable for package Makefiles similar to
PKG_FLAGS. It's a whitespace separated list of flags to control various
aspects of how a package is build.
The build system and/or .config defines the default for each, but
every package has the means to override it. Using $flagname enables
a flag, no-$flagname disables it.
Start with PKG_IREMAP as "iremap". That's easy as no package here
nor in any package feed uses it. The default is unchanged: enabled.
Packages can opt-out via:
PKG_BUILD_FLAGS:=no-iremap
(Not that any should, just to illustrate how to use it)

While experimenting with the AUTOREMOVE option in search of a way to use
prebuilt host tools in different buildroot, it was discovered that the
md5 generated by find_md5 in depends.mk is not reproducible.
Currently the hash is generated by the path of the file in addition to
the file mod time. Out of confusion, probably, there was an idea that
such command was used on the package build_dir. Reality is that this
command is run on the package files. (Makefile, patches, src)
This is problematic because the package Makefile (for example) change at
each git clone and base the hash on the Makefile mtime doesn't really
reflect if the Makefile actually changes across a buildroot or not.
A better approach is to generate an hash of each file and then generate
an hash on the sort hash list. This way we remove the problem of git
clone setting a wrong mtime while keeping the integrity of checking if a
file changed for the package as any change will result in a different
hash.
Introduce a new kind of find_md5 function, find_md5_reproducible that
apply this new logic and limit it only with AUTOREMOVE option set to
prevent any kind of slowdown due to additional hash generation.

Package with whitespace in their build directory are not correctly
removed when CONFIG_AUTOREMOVE is enabled. This is caused by xargs that
use whitespace as delimiters. To handle this use \0 as the delimiter and
set find to use \0 as the delimiter.

4e19cbc5533: [download: handle possibly invalid local tarballs] added a
FORCE rule to downloaded files, so that they will be always checked by
download.pl.
As a side-effect, check-compile will fail, forcing unnecessary package
rebuilds.
The check-compile.txt log shows (for libxml2 for example):
Considering target file '.../dl/libxml2-2.9.12.tar.gz'.
...
prerequisite 'FORCE' of target '.../dl/libxml2-2.9.12.tar.gz' does
not exist.
Must remake target '.../dl/libxml2-2.9.12.tar.gz'.
...
Giving up on target file '...libxml2-2.9.12/.prepared_...'.
Giving up on target file '...libxml2-2.9.12/.configured_...'.
Giving up on target file '...libxml2-2.9.12/.built'.
Giving up on target file '...stamp/.libxml2_installed'.
Giving up on target file '.compile'.
Then the package is rebuilt even if it is not otherwise needed.
To fix this, instead of always forcing the download target to be remade,
check its hash first: if it matches, then the FORCE is not added.

Currently it's assumed, that already downloaded tarballs are always
fine, so no checksum checking is performed and the tarball is used even
if it might be corrupted.
From now on, we're going to always check the downloaded tarballs before
considering them valid.
Steps to reproduce:
1. Remove cached tarball
rm dl/libubox-2020-08-06-9e52171d.tar.xz
2. Download valid tarball again
make package/libubox/download
3. Invalidate the tarball
sed -i 's/PKG_MIRROR_HASH:=../PKG_MIRROR_HASH:=ff/' package/libs/libubox/Makefile
4. Now compile with corrupt tarball source

Set CCACHE_DIR to $(TOPDIR)/.ccache and CCACHE_BASEDIR to $(TOPDIR).
This allows to do clean and dirclean. Cache hit rate for test build
after dirclean is ~65%.
If CCACHE is enabled stats are printed out at the end of building process.
CCACHE_DIR config variable allows to override default, which could be useful
when sharing cache with many builds.
cacheclean make target allows to clean the cache.
Changes from v1:
- remove ccache directory using CCACHE_DIR variable
- remove ccache leftovers from sdk and toolchain make files
- introduce CONFIG_CCACHE_DIR variable
- introduce cacheclean make target

Extend the packageauxvars database to keep a list of possible package

This fixes two issues with cleaning package files from STAGING_DIR:
* CleanStaging currently can only remove files and not directories. This
changes CleanStaging to use clean-package.sh, which does remove
directories.
* Because of the way directories are ordered in the staging files list,
clean-package.sh currently tries (and fails) to remove parent
directories before removing subdirectories. This changes
clean-package.sh to process the staging files list in reverse, so that
subdirectories are removed first.

When CONFIG_AUTOREMOVE is enabled, the build system touches an additional
".autoremove" stamp file in the cleaned build directory.
Since the autoremove stamp file is touched after the compile process
completed, it ends up being the most recent file of the package build
directory, causing the timestamp.pl check of depends.mk to erroneously
declare the ".built" and ".prepared" stamp files as stale, triggering
a forced clean-build submake process.
Fix the problem by using the ".built" stamp file as modification time
reference when touching the ".autoremove" stamp file.

Some packages, e.g. busybox, explicitly remove old .configured stamps
before attempting configuration, rather than after the actual configuration
step. This seems like a good idea, as there will be no stamp left if
configuration fails. Change generic rules to work like this, so package-
specific rules can be dropped.
