The semantics of the sun loader on 68k based machines is that the output
of ld is a 68010 binary if all the input files are 68010, and a 68020
binary if any of the input files is 68020.

Gnu ld compiled for a sun2 always makes a 68010 executable, even when
linking in a 68020 object.  And compiled for a sun3, always a 68020
executable.  Here we have both sun2's and sun3's, and it's desirable to
be able to make either type of binary (we can get either type of .o
file with gcc and gas).

PS -- Should the return type of "fread" in "gprof.c" be "size_t"?  K&R2
says so, but that's not authoritative.
