This simplifies the 'make' commands for most of nolibc supported
architectures, only requires the XARCH option now.
Almost all distributions provide qemu and toolchains for i386, x86_64,
arm64, arm, mips, riscv and s390, let's customize the local toolchains
for them. The fresh new loongarch is an exception, which is not covered
here.
If want to use another toolchain which is not customized here, we can
also pass CROSS_COMPILE, CROSS_COMPILE_$(XARCH) and even CC from command
line.
After carefully install and configure $(CROSS_COMPILE_$(XARCH)) and
qemu-$(XARCH), it is able to run tests for the architectures or their
variants like this:
$ 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

riscv: 165 test(s): 156 passed, 9 skipped, 0 failed => status: warning
