[PATCH 0/3] selftests/nolibc: various build improvements

[Thomas Weißschuh]

With the out-of-tree builds it's possible do incremental tests fairly fast:

time ./run-tests.sh 
i386:          162 test(s): 162 passed,   0 skipped,   0 failed => status: success
x86_64:        162 test(s): 162 passed,   0 skipped,   0 failed => status: success
arm64:         162 test(s): 162 passed,   0 skipped,   0 failed => status: success
arm:           162 test(s): 162 passed,   0 skipped,   0 failed => status: success
mips:          162 test(s): 161 passed,   1 skipped,   0 failed => status: warning
ppc:           162 test(s): 162 passed,   0 skipped,   0 failed => status: success
ppc64:         162 test(s): 162 passed,   0 skipped,   0 failed => status: success
ppc64le:       162 test(s): 162 passed,   0 skipped,   0 failed => status: success
riscv:         162 test(s): 162 passed,   0 skipped,   0 failed => status: success
s390:          162 test(s): 161 passed,   1 skipped,   0 failed => status: warning
loongarch:     162 test(s): 161 passed,   1 skipped,   0 failed => status: warning

real	1m56.226s
user	2m42.457s
sys	0m57.979s

This is with an incremental kernel rebuild and testrun inside qemu.
