Hi, Willy

Now, the dependent pmac32_defconfig patch has been merged into the
powerpc next-test branch [1] ;-)

v6 here with a clean up of the CFLAGS for ppc variants, removed the
redundant -Wl options and call cc-option to check the -mmultiple option
for llvm as kernel does. v5 is [2].

Tests run with local toolchains and latest toolchains.

    $ for arch in ppc ppc64 ppc64le; do \
        make run-user XARCH=$arch | grep "status: "; \
      done
    166 test(s): 158 passed,   8 skipped,   0 failed => status: warning
    166 test(s): 158 passed,   8 skipped,   0 failed => status: warning
    166 test(s): 158 passed,   8 skipped,   0 failed => status: warning

    $ for arch in ppc ppc64 ppc64le; do \
        make run-user XARCH=$arch CC=/labs/linux-lab/prebuilt/toolchains/ppc64/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc | grep "status: "; \
      done
    166 test(s): 158 passed,   8 skipped,   0 failed => status: warning
    166 test(s): 158 passed,   8 skipped,   0 failed => status: warning
    166 test(s): 158 passed,   8 skipped,   0 failed => status: warning

Changes from v5 --> v6:

* selftests/nolibc: add test support for ppc
  selftests/nolibc: add test support for ppc64le
  selftests/nolibc: add test support for ppc64

    Removed the -Wl options.

    As comment from arch/powerpc/Makefile, use -mmultiple with cc-option for llvm has no such options.

* tools/nolibc: add support for powerpc
  tools/nolibc: add support for powerpc64
  selftests/nolibc: add XARCH and ARCH mapping support
  selftests/nolibc: allow customize CROSS_COMPILE by architecture
  selftests/nolibc: customize CROSS_COMPILE for 32/64-bit powerpc

    No changes.


BR,
Zhangjin Wu
