I'm not against it, but I would like your opinion on a question...

Moving the whole of powerpc64 to powerpc64-common, leaves powerpc64 empty,
which I can then fill with files that are specific to big-endian.  On the
other hand, if I move things into powerpc64/common, then powerpc64 is not
empty and Implies files on powerpc64le will still point to powerpc64 (but
now to the common subdir).  This gives a little less separation, imo, and
that's why I came up with powerpc64-common outside of powerpc64.

However, it could have its disadvantages. Do you have an opinion on that?
