These parts look like newlib bugs:

The other part:

/tmp/mainline/objdir/gcc/../../combined/gcc/libgcc2.c:1680: undefined reference to `_atexit'
is a GCC bug but it might also be a newlib bug

I'm not so sure, but I'll ask newlib...

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.

If the i960 port really is dead, why don't we deprecate it in 3.4 (or even remove it)? As for those 
who claim they need it, they can always keep the current source. I just don't see the point in 
keeping something nonbuildable and unmaintained in the tree. What you think?

I have recommended it for deprecation every time the subject has come
up.  So far, I haven't been successful.  We have mainly been doing non
controversial deprecations, e.g. if anyone claims they need a port, we
don't deprecate it.  Every time I've tried to get the i960 port
deprecated, someone has claimed that they needed it.  No one has ever
stepped forward to help fix bugs in it though, and I haven't seen any
evidence that anyone is actually trying to use it.  Eventually, the
stalemate will be broken, but for now, it remains an unmaintained and
often unbuildable port.

suspending it based on the fact it is on the list to deprecation (and no one has 
complained yet :) ).

Guess what this configuration has been removed for 3.5.0.
