[Openmp-commits] [openmp] [OpenMP][lit] Disable flaky tasking/issue-94260-2.c on s390x too (PR #233384)

[Abid Qadeer via Openmp-commits]

https://github.com/abidh created https://github.com/llvm/llvm-project/pull/233384

b217e5c5a035 marked this test UNSUPPORTED on x86 Linux because it fails sporadically; the underlying problem is tracked in #176451, which is still open. The arch qualifier keeps it enabled everywhere else, so the s390x bot still runs it and hits the same failure. In the last 100 builds of openmp-s390x-linux (28089-28188), it was the only failing test in each of the 4 failed builds:

  https://lab.llvm.org/buildbot/#/builders/88/builds/28117
  https://lab.llvm.org/buildbot/#/builders/88/builds/28151
  https://lab.llvm.org/buildbot/#/builders/88/builds/28186
  https://lab.llvm.org/buildbot/#/builders/88/builds/28188

In 28188 it crashed with SIGSEGV and no output, and the only change in the blamelist was a documentation fix (#232296). Add s390x to the arch list so the bot stops blaming unrelated commits while #176451 is open.
