It shouldn't be providing liblapack.so.3 at all; the bogus provide can
be filtered out by doing something like this:

# Don't "provide" our private libs, or generate doc-file dependencies
%global _use_internal_dependency_generator 0
%global docfilt perl -p -e 's|%{_docdir}/%{name}-%{version}\\S+||'
%global so_filt grep -v '%{_libdir}/atlas/.*$'
%global __deploop() while read FILE; do /usr/lib/rpm/rpmdeps -%{1} ${FILE}; done | /bin/sort -u
%global __find_provides /bin/sh -c "%{so_filt} | %{__deploop P}"
%global __find_requires /bin/sh -c "%{docfilt} | %{__deploop R}"

This is how the filtering macros described at
https://fedoraproject.org/wiki/Packaging:AutoProvidesAndRequiresFiltering
work, but they're only available in recent Fedora releases.
