Fix 32-bit RPM build w/ newer RHEL/Fedora releases

The version of RPM on RHEL 5 and older platforms defines _libdir
as %{_exec_prefix}/%{_lib}, so defining _lib in the spec file redefined
_libdir.  However, newer versions of RPM (probably >= 4.6, since that
was the version that introduced the ISA macros) define _libdir as either
%{_prefix}/lib or %{_prefix}/lib64.  Thus, we need to explicitly
override _libdir in our spec file.
