Before glibc-devel was split into glibc-devel and glibc-headers, it was
possible if glibc-devel*.i386.rpm was installed after glibc-devel*.x86_64.rpm
that you had the IA-32 /usr/include headers which support only -m32
(unlike x86_64 /usr/include headers which support both -m32 and -m64).
The change was done on Sep, 2nd in glibc 2.3.2-79.
Uninstalling both glibc-devel's (with --nodeps) and then installing
them again in the right order (rpm -i glibc-devel*.i386.rpm glibc-devel*.x86_64.rpm)
should cure it.

I don't claim this must be this problem (the preprocessed source which
results in this incorrect assembly would tell exactly where the problem is),
but the errors which were caused by this looked exactly the same.
