Hi. Can we get this working? There're many packages that
Build-Depends: (stuff that eventually depends on BLAS)
and those can't be cross-built right now.
The main proposal from #760936 was to manage a separate alternative for
each architecture. There's precedent for this at least in src:petsc and
src:s2tc.
I'm attaching a patch series that applies this idea here. The patches
mostly work. There're at least two bugs here that need to be dealt with,
and I can work on those. But in the meantime, let's decide that this is
the approach we want to pursue. The issues:
1. Something is wrong with libblas.a. It ends up mostly empty for me
2. There's now a separate set of alternatives for each arch called
something like blas-ARCH. Installing one of the new packages creates
these new alternatives, but doesn't remove the old alternatives, which
end up as a broken link.
Clearly, we'd also need to update the other packages that provide BLAS
implementations, but let's do this one step at a time.

Subject: [PATCH 4/4] libblas-dev no longer Depends:gfortran
This is wrong for cross-building. There's a plan to make these types of
dependencies work generically, but we're not there yet. In the meantime, this
dependency isn't very useful: a user who's savvy enough to install -dev packages
and compile stuff knows that they need a compiler.
