To build an ELF kernel on mac68k with only 'option M68040' (not M68020
or M68030), I need the following. Does this look correct?

There are also two places in "locore.s" where both arguments to
ALTENTRY() have leading underscores. I'm a little confused about how
that's supposed to work. From inspecting <m68k/asm.h>, it looks to me as
if ALTENTRY() would add one too many underscores in the a.out case.
[There was one report to port-mac68k that profiling seems to be broken,
but the poster didn't say if he was building with PROF or GPROF or a.out
or ELF.] Is the right thing to do to just drop all the underscores?
