Add a set of skip files for running the syscalls set of tests in compat or purecap: - syscalls_morello_musl_skip skips all Musl related failures, - syscalls_morello_skip is for skipped and not built tests in compat, - syscalls_morello_purecap_skip is for tests skipped in purecap.
Update the README to reflect those additions and explain how to use the skip files.
This is preparation for CI testing in Morello release 1.6 and later.
Signed-off-by: Teo Couprie Diaz teo.coupriediaz@arm.com --- v4: - Some README rephrasing to address Beata's comments - Changed kernel version dependency comment in the musl skip file - Renamed all skip files to accomodate for a purecap one - Added purecap skip file - Updated README and commit message for purecap skip file v3: - Added *_16 tests to the skip list - Added tests from kernel/security as we don't build them yet - Mentioned Morello 1.6 release v2: - Removed mentions of COMPAT - Reworded comment around Alpine - Added bpf_prog02 to the musl skips after further testing
