[PATCH v1 0/4] selftests/nolibc: customize CROSS_COMPILE for all supported architectures

[Zhangjin Wu <falcon@tinylab.org>]

Hi, Willy

Based on the CROSS_COMPILE customize support [1] from the last ppc
patchset, to further make run-user/run targets happy for all of the
nolibc supported architectures, let's customize CROSS_COMPILE for all of
them.

Beside loongarch, all of the other architectures have local toolchains.
let's use the one from [2] for loongarch, it has a different prefix.

And also, as suggested by you in our previous discuss, let's add some
notes for the toolchains and firmwares instead of automatically download
them.

Now, the test iteration becomes very simple and pretty:

    $ ARCHS="i386 x86_64 arm64 arm mips ppc ppc64 ppc64le riscv s390"
    $ for arch in ${ARCHS[@]}; do printf "%9s: " $arch; make run-user XARCH=$arch | grep status; done
         i386: 165 test(s): 157 passed,   8 skipped,   0 failed => status: warning
       x86_64: 165 test(s): 157 passed,   8 skipped,   0 failed => status: warning
        arm64: 165 test(s): 157 passed,   8 skipped,   0 failed => status: warning
          arm: 165 test(s): 156 passed,   9 skipped,   0 failed => status: warning
         mips: 165 test(s): 156 passed,   9 skipped,   0 failed => status: warning
          ppc: 165 test(s): 157 passed,   8 skipped,   0 failed => status: warning
        ppc64: 165 test(s): 157 passed,   8 skipped,   0 failed => status: warning
      ppc64le: 165 test(s): 157 passed,   8 skipped,   0 failed => status: warning
        riscv: 165 test(s): 156 passed,   9 skipped,   0 failed => status: warning
         s390: 165 test(s): 156 passed,   9 skipped,   0 failed => status: warning

(I have no qemu-user currently for loongarch, so, no test result above)

Best regards,
Zhangjin
