Some comments with regard to IA-64:

1) I'd rather have the declarations for
   ia64_linux_sigcontext_register_address() and
   ia64_aix_sigcontext_register_address() go into a single ia64-tdep.h
   file.  I think having two files is overkill.

2) However, even that shouldn't be necessary.  Now that we have the
   OSABI machinery, it should be possible to solve the problem without
   having to export these functions at all.
