I need the 32-bit multiply and divide support functions
__mulsi3, __divsi3, __udivsi3, __modsi3, and __umodsi3.

Ya, what this short Makefile.inc fragment does is extract their
objects from libgcc.a and then add them to libkern's OBJS, so they 
do end up in the libkern that things get linked with.  I guess we 
could write our own equivalent C or assembler replacements under 
sys/lib/libkern/arch/m68k, but I didn't think I had to.
