Interesting.  I can't find the source file you mention (ld-callob.c);
can you check the filename?   Is it generated during the build?

For what it's worth, here's a link that discusses this error message:
   http://gcc.gnu.org/PR11442
Sounds like a glibc issue, offhand.

I haven't tried --with-cpu=iwmmxt myself.  It's fairly new
(http://gcc.gnu.org/ml/gcc-patches/2003-06/msg02098.html)
so perhaps nobody's built glibc with it yet.
