selftests/nolibc: add script to run testsuite
The script can run the testsuite for multiple architectures and provides an overall test report. Furthermore it can automatically download crosstools from mirrors.kernel.org if requested by the user. Example execution: $ ./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 Signed-off-by: Thomas Weißschuh <linux@weissschuh.net> Acked-by: Willy Tarreau <w@1wt.eu> Link: https://lore.kernel.org/r/20231105-nolibc-run-tests-v1-1-b59ff770a978@weissschuh.net
