[ This has a fix for powerpc md_init.h, bug found by brad ]

.init and .fini are not quite set up like some programs desire.
I was under the impression that only some systems expect the .init
section to be an instruction stream. However it seems this is not the
case. Only on i386 have I seen code which expects this behavior, however
it makes sense to fix this properly. This change paritally comes from
NetBSD, however it is a much simpler implementation of that hairy mess.

The code which currently uses the 'other behavior' in .init/.fini
is wine.
