Hi, Willy, Thomas
The suggestions of v1 nolibc powerpc patchset [1] from you have been applied,
here is v2.
Testing results:
- run with tinyconfig

Changes from v1 --> v2:
- tools/nolibc: add support for powerpc
Add missing arch-powerpc.h lines to arch.h
Align with the other arch-<ARCH>.h, naming the variables
with more meaningful words, such as _ret, _num, _arg1 ...
Clean up the syscall instructions
No line from musl now.
Suggestons from Thomas
* tools/nolibc: add support for pppc64
No change
* selftests/nolibc: add extra configs customize support
To reduce complexity, merge the commands from the new extraconfig
target to defconfig target and drop the extconfig target completely.
Derived from Willy's suggestion of the tinyconfig patchset
* selftests/nolibc: add XARCH and ARCH mapping support
To reduce complexity, let's use XARCH internally and only reserve
ARCH as the input variable.
Derived from Willy's suggestion
* selftests/nolibc: add test support for powerpc
Add ppc as the default 32-bit variant for powerpc target, allow pass
ARCH=ppc or ARCH=powerpc to test 32-bit powerpc
Derived from Willy's suggestion
* selftests/nolibc: add test support for pppc64le
Rename powerpc64le to ppc64le
Suggestion from Willy
* selftests/nolibc: add test support for pppc64
Rename powerpc64 to ppc64
Suggestion from Willy
Best regards,
Zhangjin
