#     selftests/powerpc: Always build the tm-poison test 64-bit
#     
#     The tm-poison test includes inline asm which is 64-bit only, so the
#     test must be built 64-bit in order to work.
#     
#     Otherwise it fails, eg:
#       # file tm-poison
#       tm-poison: ELF 32-bit MSB executable, PowerPC or cisco 4500, version 1 (SYSV) ...
#       # ./tm-poison
#       test: tm_poison_test
#       Unknown value 0x1fff71150 leaked into f31!
#       Unknown value 0x1fff710c0 leaked into vr31!
#       failure: tm_poison_test
#     
#     Fixes: a003365cab64 ("powerpc/tm: Add tm-poison test")
