Expand rpm macros when using the release in a path
    
    The release tag commonly uses system-configured macros (%{dist}). In
    order to match the paths used by rpmbuild, evaluate the release tag with
    rpm any time it is used to generate a path.
    
    The name, version, and arch tags could also potentially contain macros,
    but it makes less sense for these fields to use macros that are not
    dependent on definitions within the spec file itself.
