Pull up following revision(s) (requested by martin in ticket #80):
        usr.sbin/installboot/Makefile: revision 1.53
        usr.sbin/installboot/Makefile: revision 1.54
        usr.sbin/installboot/machines.c: revision 1.41
        usr.sbin/installboot/machines.c: revision 1.42
Replace black voodo linker magic (sometimes failing) with some
makefile + macro magic to trim the list of available machines on size
restricted install media.
Never trust a compiler that predefines i386 as 1 - do the symbol name
concatenation at the make level instead.
