I'm pretty sure according to our discussion on the proper placement of
libgcc_eh that there is a missing "-lgcc_eh" right here (or rather the
next one should be _after_ the crtbegin?). See the wrapping -lgcc_eh 
around -lc and -lgcc

This is an issue we've seen in the detection of unwind info from
autoconf. Glibc has a patch to hack around a proper detection by placing
the appropirate -lgcc_eh in the front.
