[PATCH AUTOSEL 5.4 038/134] selftests/powerpc: Skip tm-signal-sigreturn-nt if TM not available

From: Michael Ellerman <mpe@ellerman.id.au>

[ 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.

Fixes: 34642d70ac7e ("selftests/powerpc: Add checks for transactional sigreturn")
