- make all ports egcs; move stuff to mi and shl.*
- fix m68k-based comp sets to use usr/include/$MACHINE (as
usr/include/machine is now a symlink); add directory entries where missing
lint libs.
2) on some md.* files, change "/machine/" to "/$ARCH/" to reflect the
new way we do /usr/include/machine include files.
Note that some archs probably need md lint libs added, and some
machines probably still need their /usr/include/machine support
frobbed, but it is a good start.
