Subject: [PATCH v4 00/12] tools/nolibc: add 32/64-bit powerpc support

Hi, Willy, Hi Thomas

v4 here is mainly with a new nolibc-test-config target from your
suggestions and with the reordering of some patches to make
nolibc-test-config be fast forward.

run-user tests for all of the powerpc variants:

    $ for arch in ppc ppc64 ppc64le; do make run-user XARCH=$arch | grep status; done
    165 test(s): 157 passed,   8 skipped,   0 failed => status: warning
    165 test(s): 157 passed,   8 skipped,   0 failed => status: warning
    165 test(s): 157 passed,   8 skipped,   0 failed => status: warning

and defconfig + run for ppc:

    $ make nolibc-test-config XARCH=ppc
    $ make run XARCH=ppc 
    165 test(s): 159 passed,   6 skipped,   0 failed => status: warning


* tools/nolibc: add support for powerpc
  tools/nolibc: add support for powerpc64

    No change.

* selftests/nolibc: fix up O= option support
  selftests/nolibc: add macros to reduce duplicated changes

    From tinyconfig-part1 patchset, required by our nolibc-test-config target

    Let nolibc-test-config be able to use objtree and the kernel related
    macros directly.

* selftests/nolibc: add XARCH and ARCH mapping support

    Moved before nolibc-test-config, for the NOLIBC_TEST_CONFIG macro used by
    nolibc-test-config target
    
    Willy talked about this twice, let nolibc-test-config be able to use
    nolibc-test-$(XARCH).config listed in NOLIBC_TEST_CONFIG  directly.

* selftests/nolibc: add nolibc-test-config target
  selftests/nolibc: add help for nolibc-test-config target

    A new generic nolibc-test-config target is added, allows to enable
    additional options for a top-level config target.

    defconfig is reserved as an alias of nolibc-test-config.

    As suggested by Thomas and Willy.

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

    Renamed from $(XARCH).config to nolibc-test-$(XARCH).config

    As suggested by Willy.

* selftests/nolibc: allow customize CROSS_COMPILE by architecture
  selftests/nolibc: customize CROSS_COMPILE for 32/64-bit powerpc

    Moved here as suggested by Willy.

Best regards,
Zhangjin
