The i960 port is effectively dead.  It has been unmaintained for several 
years.  I keep trying to kill it, but people who aren't willing to 
maintain it themselves keep claiming that they need it, so it continues 
on, half-dead and half-alive.

I don't really care, but I'm guessing that the problem is LIB_SPEC 
doesn't include -lc, on the assumption that it will be provided by the 
linker script.  Some embedded ports will only build if you specify the 
linker script.  Maybe putting -Wl,-Tmon960.ld in CFLAGS_FOR_TARGET in 
the toplevel Makefile would work?  Or maybe we should redesign how this 
stuff works.

Note that gcc/config/libgloss.h sets LIB_SPEC to a null string.
