Well, isn't that exposing problems that exist today, rather than adding
new ones (ie the problem is that an unexpected (OE-built) libfoo is
used) ?

It would be a good idea, I think, to 'time' a few builds like this, to
see how much time we save not building libgfortran (and the java one
too) and how much time we do or don't save by building libstdc++ on its
own.
