m68k assembler (and MRI tools)

Werner-

I tried your script with your versions. binutils-2.12.1 choked (sorry,
but I nuked it before logging where - it was in the same "no targets
for libiberty" that we've all seen before).

I replaced binutils with 2.13 and everything built fine. I modified
the sequence a little (Dan Kegel's autoconf fix, and a position-
independent code patch for gcc-2.95.3).
