The -cc wrapper can be used for linking and can fail if key flags are missing:
| error: linking with `[path]/tmp/work/x86_64-linux/rust-native/1.54.0-r0/wrapper/target-rust-cc`
Add the flags to fix builds even if that is counter-intuitive (cc would
normally be used for compiling and ccld for linking).

The oeqa selftest test:
sstatetests.SStateTests.test_sstate_sametune_samesigs
which checks if the sstate checksums of two identical machines
(using the same tune) are the same, apart from changes within
the machine specific stamps directory, fails on the assertion:
self.assertCountEqual(files1, files2)
due to the signature of various 32 bit package builds such as:
x86_64-linux/lib32-rust-cross-i686
x86_64-linux/rust-cross-i686
x86-pokymllib32-linux/lib32-libstd-rs
x86-pokymllib32-linux/lib32-rust
differing. Jumping down the rabbit hole past all the bitbake-diffsig
outputs that differ due to dependent hashes, you come to a diff of:
-Variable MACHINEOVERRIDES value is ${@bb.utils.contains('TUNE_FEATURES', 'mx32', 'x86-x32:', '', d)}${@bb.utils.contains('TUNE_FEATURES', 'm32', 'x86:', '', d)}qemuall:${MACHINE}
+Variable MACHINEOVERRIDES value is ${@bb.utils.contains('TUNE_FEATURES', 'mx32', 'x86-x32:', '', d)}${@bb.utils.contains('TUNE_FEATURES', 'm32', 'x86:', '', d)}qemuall:${MACHINE}:qemux86
in
stamps/x86_64-linux/rust-cross-i686/1.54.0-r0.do_rust_gen_target.<sig>
This is because there are two rust functions referencing OVERRIDES
related variables (target_is_armv7 and llvm_features_from_tune). These
indirectly influnce the build and should be excluded from the signatures
directly as is done in other toolchain recipes, e.g.:
39bfa0dd32 recipes/*-cross recipes: ignore TARGET_ARCH sstate hash
