Pgowda 8c5e589df8 rust-cross: Replace TARGET_ARCH with TUNE_PKGARCH
rust-cross-* imported from meta-rust has incorrect signatures,
depending on MACHINEOVERRIDES making it effectively MACHINE_ARCH
as shown by sstate-diff-machines.sh:

openembedded-core/scripts/sstate-diff-machines.sh --tmpdir=tmp-glibc \
--machines="qemuarm64 qemuarm64copy" --targets=rust-cross-aarch64-glibc \
--analyze

 === Comparing signatures for task do_configure.sigdata between
 qemuarm64 and qemuarm64copy ===
ERROR: gcc-runtime different signature for task do_configure.sigdata
between qemuarm64 and qemuarm64copy

47a0ebb7a88c9f896fb9dbce269f575ab8a6faabb2b9e62d164be6e71c5e4e40

The following patch takes TUNE_PKGARCH into consideration instead
of TARGET_ARCH and results in signatures as expected.

[YOCTO #14613]

RP: Added maintainer.inc corresponding change
(From OE-Core rev: bcf48766d1123cea41f80b0cb687584692c96158)
