Hi, Willy, Thomas

Here is the revision of the v2 arch support shrink patchset [1], it
mainly applies suggestions from you.

It is based on the 20230710-nolibc-ser2-tom-syscall-configv4-report
branch of nolibc repo.

Tested for all of the supported archs:

           arch/board | result
          ------------|------------
      arm/versatilepb | 151 test(s): 144 passed,   7 skipped,   0 failed => status: warning.
      arm/vexpress-a9 | 151 test(s): 144 passed,   7 skipped,   0 failed => status: warning.
             arm/virt | 151 test(s): 144 passed,   7 skipped,   0 failed => status: warning.
         aarch64/virt | 151 test(s): 144 passed,   7 skipped,   0 failed => status: warning.
              i386/pc | 151 test(s): 144 passed,   7 skipped,   0 failed => status: warning.
            x86_64/pc | 151 test(s): 144 passed,   7 skipped,   0 failed => status: warning.
         mipsel/malta | 151 test(s): 144 passed,   7 skipped,   0 failed => status: warning.
     loongarch64/virt | 151 test(s): 144 passed,   7 skipped,   0 failed => status: warning.
         riscv64/virt | 151 test(s): 144 passed,   7 skipped,   0 failed => status: warning.
         riscv32/virt | 151 test(s): 122 passed,   7 skipped,  22 failed => status: failure.
s390x/s390-ccw-virtio | 151 test(s): 144 passed,   7 skipped,   0 failed => status: warning.

Changes from v2 --> v3:

* tools/nolibc: remove the old sys_stat support

    Revert the reorg operation, basically the same as v1

* tools/nolibc: add new crt.h with _start_c

    Revert the reorg operation
    Add crt.h in Makefile
    Add _nolibc_main alias for main to silence the compile warning about 

* tools/nolibc: arm: shrink _start with _start_c
  tools/nolibc: aarch64: shrink _start with _start_c
  tools/nolibc: i386: shrink _start with _start_c
  tools/nolibc: x86_64: shrink _start with _start_c
  tools/nolibc: mips: shrink _start with _start_c
  tools/nolibc: loongarch: shrink _start with _start_c
  tools/nolibc: riscv: shrink _start with _start_c
  tools/nolibc: s390: shrink _start with _start_c

    Revert the reorg operation, but still use post-whitespaces instead of post-tab.
    Include "crt.h" in arch-<ARCH>.h

* tools/nolibc: arch-*.h: add missing space after ','

    Fix up the errors reported by scripts/checkpatch.pl

Best regards,
Zhangjin
