- make all ports egcs; move stuff to mi and shl.*
- fix m68k-based comp sets to use usr/include/$MACHINE (as
usr/include/machine is now a symlink); add directory entries where missing
* factor all m68k common stuff into lists/*/ad.m68k
XXX: this should be done for mips (when it's not just the pmax), and
powerpc (when there's a powerpc port put here ...)
