I just did, and now it fails with

.../sparc64-unknown-linux-gnu/bin/ld: cannot find -lgcc_eh
collect2: ld returned 1 exit status
make[1]: *** [.../sparc64-unknown-linux-gnu/gcc-3.4.0-glibc-20040501/build-glibc/libc.so] Error 1

Anyone know why the patch at the end of the thread
http://sources.redhat.com/ml/libc-alpha/2003-09/msg00100.html didn't go in?
I don't know how one bootstraps glibc if it requires -lgcc_eh.

Maybe I'll go back to glibc-2.3.2 and try to follow Jakub's hint:
