rpm flags shared libraries of ELFCLASS64 with '(64bit)' on all architectures except Alpha (which thankfully we don't support). My question is, are ELFCLASS64 libraries always installed in /usr/lib64 on all Fedora platforms, or am I going to have to read the elf class of the file to be sure?

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...

not sure why you think you need to specify that explicitly while rpmbuild does that on it's own, but anyways, you would likely use soemthing like that
libblas.so.3%{?_isa}
https://fedoraproject.org/wiki/Packaging:Guidelines and look for %{?_isa} there as well as http://www.rpm.org/wiki/PackagerDocs/ArchDependencies

%if %{__isa_bits} = 64 Requires: libFOO.so.X()(64bit) %else Requires: libFOO.so.X %endif
