Have you read
http://kegel.com/crosstool/current/doc/crosstool-howto.html#mac
?  It doesn't sound like it, offhand.  You most certainly
can use gnu ld and as; crosstool is going to be generating
Linux binaries, not Mac OS X binaries.

That sounds familiar.  Maybe if you pasted in the few lines in the
log around the error, I could dredge it up.

There's at least one other report of this:

Try installing Fink's ld and as... can't hurt.
Maybe the real fix for your stddef.h problem would help, too.
