I'd be willing to, but it wouldn't then also get access to new files
that appear in the test suite, (where the Makefiles could actually find
new, uncopied source files).

But wait, what am I thinking... the whole approach of the non-srcdir
builds as currently implemented also copies the Makefiles. So nothing at
all is going to work without re-running configure for non-srcdir builds.

I suppose that what we want is for configure to automatically add
dependencies for every file that it copies. Then if any of these copied
files get changed in the srcdir, configure would be run again.

That should be pretty slick, I think.
