Right, but

  %{!mpowerpc*: %(asm_default)}} \

instead, since the -mpower option is no more.

I didn't even pick the wrong condition branch there: the original
code does not do the right thing for "gcc -mno-power", which is
effectively always on after my patch.  But let's not always do
the wrong thing; patch coming up (it needs changing in a few places
more).
