currently rhel-9.2.0 builds (as of glibc-2.34-60.el9_2.16) show test failures on i686:

=====FAIL: elf/tst-cpu-features-supports.out=====
=====FAIL: elf/tst-cpu-features-supports.test-result=====
=====FAIL: elf/tst-cpu-features-supports-static.out=====
=====FAIL: elf/tst-cpu-features-supports-static.test-result=====

and on s390x:

=====FAIL: rt/tst-cpuclock2.out=====
=====FAIL: rt/tst-cpuclock2.test-result=====

with the former present in the previous build as well (glibc-2.34-60.el9_2.15) and the later looks like intermittent one (not present in the latest build but found in identical scratch build) and can possibly be addressed by:

Remove unreliable parts of rt/tst-cpuclock2

This is a follow-up to the tst-cpuclock1.c change here:
9a29f1a2ae3d4bb253ee368e0d71db0ca9494120

This test, like tst-cpuclock1, may fail on heavily loaded VM
servers (and has occasionally failed on the 32bit trybot),
so tests that rely on "wall time" have been removed.
