This branch exhibits the same problem with regards to x86 and Clang as reported on 6.4 [1].

(An old warning is restored in tools/testing/selftests/rseq/, now that it builds again, but it was there in 6.1.44 too, so this is not a newly introduced warning. This is the warning:
-----8<-----

As expected, this reappeared due to Broonie's patch to fix rseq's build ("selftests/rseq: Fix build with undefined __weak").)
