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.
