While some setups, like Debian, provide a symlink to execute

Avoid applying the workaround on clang, as clang does not recognize

tools/nolibc: add support for [v]sscanf()
Revert "selftests: kselftest: Fix build failure with NOLIBC"
tools/include/nolibc/stdio.h
This reverts commit 16767502aa990cca2cb7d1372b31d328c4c85b40.
Nolibc gained support for uname(2) and sscanf(3) which are the
dependencies of ksft_min_kernel_version().
So re-enable support for ksft_min_kernel_version() under nolibc.

All supported kernels are assumed to use struct new_utsname.
This is validated in test_uname().
uname(2) can for example be used in ksft_min_kernel_version() from the
kernels selftest framework.

run-tests.sh hides the output from the compiler unless the compilation
fails. To recognize newly introduced warnings use -Werror by default.
Also add a switch to disable -Werror in case the warnings are expected.

On musl calls to brk() and sbrk() always fail with ENOMEM.
Detect this and skip the tests on musl.

I wanted to implement sscanf() for ksft_min_kernel_version() and this is
a prerequisite for it.
It's also useful on its own so it gets its own submission.

Thomas Weißschuh (2):
tools/nolibc: add limits for {u,}intmax_t, ulong and {u,}llong
The implementation always works on uintmax_t values.
This is inefficient when only 32bit are needed.
However for all functions this only happens for strtol() on 32bit
platforms.
