My suspicion was right:

The rpm contains this:
/usr/lib64/gpc/x86_64-redhat-linux/3.4.5/

which should be
/usr/lib/gpc/x86_64-redhat-linux/3.4.5/

C.f. gcc package, which contains this:
/usr/lib/gcc/x86_64-redhat-linux/4.1.0/


So you probably need to configure with
--libdir=%{_lib}
or may-be
--libdir=%{_prefix}/lib
