Indeed, the main idea behind this patch is to make the separation between
powerpc64 and powerpc64le more clear when looking at the structure of the
directories, as well as allow them to have conflicting implementations.
It happened to be part of the requirements for the use of the alias
mechanism for _FloatN types, which I had in mind.
