Comment:

 Frustratingly enough, there isn't a direct way to do this in the Make
 system either (you're responsible for re-configuring `./libraries/integer-
 gmp/configure --with-intree-gmp`).

 I think this means that we'll need to tweak the toplevel
 `configure.ac`/`aclocal.m4` scripts to support `--with-intree-gmp` (and
 `--with-gmp-framework-preferred` while we're at it). My main question is:
 do we also need to make sure these new options do something for the old
 Make system too?
