debian/rules had support for build without mpi, as that was kept
separate in Ubuntu for main vs universe, before we allowed for source
packages in main, to have build-dependencies from universe, as long as
binaries depends are self-contained in main.

So implementing this should be easy enoug: resurrect the non-mpi build
code, tweak it to be build-profile sensitive. There was the whole lot
there - targets to regenerated control without mpi packages, and do
non-mpi build, just-mpi build, or build everything (the current
default).

I'm not sure if doxygen is still needed, as documentation build has
been broken for a while. However, I'm not sure if one can do a build
without doxygen, needs checking.
