Great.  Note that this will cause problems with some tests which
exercise compatibility symbols.  I still want to contribute the build
system changes required to support them, but I probably won't be able to
make the July 1st deadline.

(Realistically, I'd need a port which can build with
build-many-glibcs.py for that anyway.)

Thanks,
Florian
