I would like Octave to take advantage of these improvements.
Subsequently, I want to use them to further improve fsolve, lsqnonneg,
and possibly (in less immediate future) implement other optimization
routines that can benefit.

Now, what is the best way to proceed?

1. Refresh and keep maintaining a copy of qrupdate under libcruft/ in Octave.
2. Remove libcruft/qrupdate and require qrupdate to be linked.

1 is simpler. If we strive to get rid of some or all of libcruft
eventually, then maybe 2 is better, but it will make another (weak)
dependency.
The problem with a library such as qrupdate is that no distributions are
packing it at the moment. So, I'd say put it in libcruft for now, and
remove it once distributions start packing it. Of course if nobody is
packing it in a year, then I think we should remove it from libcruft to
force distributions into packing it.

The number of distributions that are keen on packaging Fortran libraries
is probably zero. Good luck in forcing them.

Then its libcruft or nothing :-)
