ld.old includes link.h in a few places (ld.h and shlib.c).

I'd like to change that to include link_aout.h. link.h right now is a
switch file which will include link_elf.h iff ELF is defined, and
link_aout.h if not. For these two files, if we're actually compiling them,
we REALLY want the aout variant, even if ELF is defined.

So does that change sound fine?

Take care,

Bill
