Patch away two things:
- %_includedir, %_oldincludedir, %_mandir, %_infodir macros from
lib/rpm/platform/*/macros to avoid cycles between outputs. Hopefully
anything doesn't really need those.
- Change %__ld, %__nm, %__objcopy, %__objdump in lib/rpm/macros to
refer to the commands in PATH. Should be safe as %__cc for instance is
already like that.
