[ Upstream commit 505127068d9b705a6cf335143239db91bfe7bbe2 ]

On systems where TM (Transactional Memory) is disabled the
tm-signal-sigreturn-nt test causes a SIGILL:

  test: tm_signal_sigreturn_nt
  tags: git_version:7c202575ef63
  !! child died by signal 4
  failure: tm_signal_sigreturn_nt

We should skip the test if TM is not available.
