Comment:
All tests are ok, except on aarch64 and aarch64-musl it's trying to build qt5, which is a dependency of qcas.

I think pari and giac are built ok before that, so I'd take this as check ok for all architectures.

I didn't change qcas at all, only revbumped and fix a xlint in the short_desc. As a matter of fact, the current version of qcas in the repos is already broken before me changing pari due to a missing symbol; maybe no one uses qcas (I don't). Anyway after this PR it works at least on x86-64 so it's definitely an improvement.
