Pull nolibc updates from Shuah Khan:
"Nolibc:
- improved portability by removing build errors with -ENOSYS
- added syscall6() on MIPS to support pselect6() and mmap()
- added setvbuf(), rmdir(), pipe(), pipe2()
- add support for ppc/ppc64
- environ is no longer optional
- fixed frame pointer issues at -O0
- dropped sys_stat() in favor of sys_statx()
- centralized _start_c() to remove lots of asm code
- switched size_t to __SIZE_TYPE__

Selftests:
- improved status reporting (success/warning/failure counts, path to
log file)
- various code cleanups (indent, unused variables, ...)
- more consistent test numbering
- enabled compiler warnings
- dropped unreliable chmod_net test
- improved reliability (create /dev/zero & /tmp, rely less on /proc)
- new tests (brk/sbrk/mmap/munmap)
- improved compatibility with musl
- new run-nolibc-test target to build and run natively
- new run-libc-test target to build and run against native libc
- made the cmdline parser more reliable against boolean arguments
- dropped dependency on memfd for vfprintf() test
- nolibc-test is no longer stripped
- added support for extending ARCH via XARCH

Other:
- add Thomas as co-maintainer"

tools/nolibc: add support for powerpc

tools/nolibc: add support for powerpc

Both syscall declarations and _start code definition are added for
powerpc to nolibc.

Like mips, powerpc uses a register (exactly, the summary overflow bit)
to record the error occurred, and uses another register to return the
value [1]. So, the return value of every syscall declaration must be
normalized to match the __sysret() helper, return -value when there is
an error, otheriwse, return value directly.

Glibc and musl use different methods to check the summary overflow bit,
glibc (sysdeps/unix/sysv/linux/powerpc/sysdep.h) saves the cr register
to r0 at first, and then check the summary overflow bit in cr0:

mfcr r0
r0 & (1 << 28) ? -r3 : r3

-->

10003c14: 7c 00 00 26 mfcr r0
10003c18: 74 09 10 00 andis. r9,r0,4096
10003c1c: 41 82 00 08 beq 0x10003c24
10003c20: 7c 63 00 d0 neg r3,r3

Musl (arch/powerpc/syscall_arch.h) directly checks the summary overflow
bit with the 'bns' instruction, it is smaller:

/* no summary overflow bit means no error, return value directly */
bns+ 1f
/* otherwise, return negated value */
neg r3, r3
1:

-->

10000418: 40 a3 00 08 bns 0x10000420
1000041c: 7c 63 00 d0 neg r3,r3

Like musl, Linux (arch/powerpc/include/asm/vdso/gettimeofday.h) uses the
same method for do_syscall_2() too.

Here applies the second method to get smaller size.
