rust: Set rustflags by environment variable
In order to use $(RUSTC_TARGET_ARCH) in HOST_BUILD_DIR, the line to
include rust-values.mk in the Rust makefile was moved in
f489e019ac4a15e974518d9928ef913a157d135a, causing it to be included
before package.mk is included.
This had the side effect of preventing "-lssp_nonshared" from being
added to RUSTC_LDFLAGS, because PKG_SSP is indirectly set by package.mk
(package.mk includes hardening.mk, hardening.mk sets PKG_SSP).
There is a deeper issue; it is the Rust package's PKG_SSP value that
causes RUSTC_LDFLAGS to be set and written to the Cargo config file. For
packages that use Rust to build, their PKG_SSP value does not affect the
linker flag.
This sets rustflags with the RUSTFLAGS environment variable, instead of
writing the value to the Cargo config file, allowing PKG_SSP from the
package being built to be used and for the package being built to modify
the rustflags used.
This also:
* Fix "-lssp_nonshared" being added to TARGET_CFLAGS instead of
RUSTC_LDFLAGS, when CONFIG_PKG_CC_STACKPROTECTOR_STRONG is set.
* Remove the use of $(RUSTC_TARGET_ARCH) in HOST_BUILD_DIR and move the
include line for rust-values.mk back to after package.mk.
Since the host build directory was moved under the target build
directory in efdbac38dc8b649ca26b49fac27abeb5cf76cd28, it is no longer
necessary to separate build directories with RUSTC_TARGET_ARCH;
$(BUILD_DIR) already separates build directories by target.
* Add BUILDONLY:=1, as the Rust package does not build a target package.
* Install the Cargo config file as "config.toml" instead of "config", as
this is the preferred form[1].
* Rename RUST_CFLAGS to RUSTC_CFLAGS and CONFIG_HOST_SUFFIX to
RUSTC_HOST_SUFFIX, for consistency.
* Allow CARGO_VARS to be set before rust-values.mk is included.
