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
f489e019ac, 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 efdbac38dc, 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.

(cherry picked from commit 37762abcb4)
This allows other packages access to RUST_ARCH_DEPENDS by including
rust-values.mk, instead of rust-package.mk which also sets
Build/Compile.

(cherry picked from commit 985738b399)
rust/host failed to compile on macOS running on Apple Silicon M1 Pro
because the host target triple is autogenerated to be
'arm64-unknown-linux-'. Rust doesn't have such a target triple, thus the
build fails because there are no pre-built artifacts for bootstrapping.
Fix this by setting RUSTC_HOST_ARCH to 'aarch64-apple-darwin' in case
our host is HOST_ARCH=arm64 and HOST_OS=darwin.

While the compiled binaries are intended to run on the host system, the
rust/host package does include the target matching the configured
OpenWrt target.
If using (for example) ./scripts/env to switch between different
OpenWrt configurations, this will cause issues if the different
configuration is for a different target. In such case there will be a
mismatch between the available Rust target and OpenWrt target and the
following error will be printed:
> error[E0463]: can't find crate for `core`
> note: the `XXX` target may not be installed
This fix will add the RUSTC_TARGET_ARCH as HOST_BUILD_DIR and CARGO_HOME
suffix, such that rust/host will be compiled in case an OpenWrt
configuration change causes the RUSTC_TARGET_ARCH to change.
