rpm flags shared libraries of ELFCLASS64 with '(64bit)' on all architectures

If you consider ia64 to be a Fedora platform - and I would totally
forgive you if you didn't - then no, %{_libdir} is /usr/lib there. But
it's not clear to me from the question why you're trying to work this
out from the file type instead of just using %{_lib} or %_{libdir}.

I want BLAS/LAPACK implementations to do something like:
%if <ELFCLASS64>
Provides: libblas.so.3()(64bit)
%else
Provides: libblas.so.3
%endif
But not sure how to construct the <ELFCLASS64> conditional. I was
hoping to avoid something like:
%(readelf -h %{_libdir}/libc.so.* | awk '$1 == "Class:" { print $2 }')
== "ELF64"
but maybe that's the way to go.
It would be interesting to know the elf class on ia64...
