While looking for enhancements to Heiko's arm relocation patches, I have
gone through all relocation related compiler and linker options, and
then some. -fPIC / -fPIE will not generate GOT fixups for data
containing pointers, and I have found no additional option that will.
OTOH, -pie will generate this kind of fixup (and all others needed) in
the form of .rel.dyn relocations, as Bill describes.

I don't mean to say that PPC relocation does not work; I mean to say
that a mechanism intended for one architecture may not be the optimal
one for another, and if two mechanisms exist which provide relocation
and one of them does not require specific tricks in the code, then I
would choose this one.
