Not sure I like that. Doesn't matter in practice as this lib doesn't
seem to change much, but I tend to follow the bundle GCC delivers and
build this stuff together as toolchain.

I will patch out libquadmath usage locally anyway now. Preferrable
would be a builtin check. A compile check for -lquadmath working?

What to do about that? Rather split out MPI and OpenMP as separate
packages, too? We don't ship the options at all right now. Would be
stupid to let them slip through now just to remove them for split
packages in the next release.

Alrighty then,
