Got it.

__udivdi3 comes from libgcc.a, which on my system is found at
/usr/lib/gcc-lib/i386-redhat-linux/2.96/libgcc.a.  A clever way to put
this in a Makefile is:

LIBGCC := $(shell $(CC) -print-libgcc-file-name)

then put ${LIBGCC} on the end of the 'ld' line.

Thank god for google.

If anyone has any links to good assembly language sites, esp. newbie
tutorial type stuff, that would be great.  Advice, admonitions, are all
welcome.  I'm thinking I'll work on gas because I'm partial to GNU.
