#     powerpc: Add -Werror at arch/powerpc level
#     
#     Back when I added -Werror in commit ba55bd74360e ("powerpc: Add
#     configurable -Werror for arch/powerpc") I did it by adding it to most
#     of the arch Makefiles.
#     
#     At the time we excluded math-emu, because apparently it didn't build
#     cleanly. But that seems to have been fixed somewhere in the interim.
#     
#     So move the -Werror addition to the top-level of the arch, this saves
#     us from repeating it in every Makefile and means we won't forget to
#     add it to any new sub-dirs.
