Some package might require to fix their pkg-config file to point to host
or hostpkg file. This is the case for glib2 library that provides with
pkg-config variables, tools to generates files from xml. Those tools
should use the host binary instead of the targets one to correctly build
packages that makes use of such tools.

Before this commit, it was assumed that pkg-config.real is in the PATH. While
this was fine for the normal build workflow, this led to some issues if
make TOPDIR="$(pwd)" -C "$pkgdir" compile
was called manually. The command failed with
Makefile:15: *** No libnl-tiny development libraries found!. Stop.
make[1]: Leaving directory
since pkg-config of the host system was used.
After the commit, the package is built sucessfully.

The pkgconf fork filters -I and -L flag values from .pc files which match
pkgconf's builtin system directory value.
During configure, pkgconf derives the default system include and library
search path values from exec_prefix, which is set to staging_dir/host in
the host tool build phase.
Due to that, pkgconf will drop all -I and -L flags pointing to
staging_dir/host/include or staging_dir/host/lib, unless invoked with
--keep-system-cflags and --keep-system-libs respectively, breaking our
kernel libelf discovery / stack validation workarounds.
In order to inhibit the filtering, add --keep-system-cflags and
--keep-system-libs to our pkg-config shell wrapper.

pkgconf is a newer, actively maintained implementation of pkg-config that
supports more aspects of the pkg-config file specification and provides a
library interface that applications can use to incorporate intelligent
handling of pkg-config files into themselves (such as build file
generators, IDEs, and compilers). Through its pkg-config compatibility
interface (activated when it is run as "pkg-config"), it also can
completely replace the original implementation.
It is also lighterweight and does not require glib2, as pkg-config does.
On other distros, pkgconf is symlinked to pkg-config. For simplicity here,
it is renamed to pkg-config.real, as in the original package.
Initial results have been positive. As before, pkgconf works as long as
the pkg-config files point to the proper paths.
