Hi, Willy

This is the revision of the v4 part2 of support for rv32 [1], this
further split the generic KARCH code out of the old rv32 compile patch
and also add kernel specific KARCH and nolibc specific NARCH for
tools/include/nolibc/Makefile too.

This is rebased on the dev.2023.06.14a branch of linux-rcu repo [2] with
basic run-user and run tests.

Changes from v4 -> v5:

* selftests/nolibc: allow customize kernel specific ARCH variable

  The KARCH customize support part splitted out of the old rv32 compile
  patch and removed the one passed to tools/include/nolibc/Makefile.

* tools/nolibc: add kernel and nolibc specific ARCH variables

  Pass original ARCH to tools/include/nolibc/Makefile, add KARCH and
  NARCH for kernel and nolibc respectively.

* selftests/nolibc: riscv: customize makefile for rv32

  Now, it is rv32 specific, no generic code.

Best regards,
Zhangjin

I already queued these two ones to relieve you from them while we
discuss the arch customization.

Thanks,
