Note that -Tidt.ld specifies:

GROUP(-lc -lidt -lgcc)

and that is the mechanism by which libc is (supposed to be) included.

were these the entire set of undefined symbols?  or were kill, getpid,
etc., in there as well?

note that kill and getpid are normally provided by libgloss, which is
normally provided by -Tidt.ld as well.

I've gotten mips-elf and similar targets to work, using the
description of how to do it on the sim testing page, as of a few weeks
ago.  I've not tried it since.
