float128 on powerpc64le requires the addition of the ieee754/float128
sysdep, whereas powerpc64 doesn't. This requires creating a bunch of
submachine and cpu directories and Implies files which just point
towards their powerpc64 equivalent.
Tested on P7, P8, and generic powerpc64le targets with and without
multiarch.
