gc 8.0.4 was submitted for inclusion into Factory. During the staging process
though, texlive resulted in a build failure

This can either be an issue in texlive (making use of code exposed in a library
it is not linking, e.g. gccpp) or gc might use them implicitly and not linking
the lib itself (possibly texlive needs a different way to identify what to
link)
