This can't be reverted without abandoning all efforts to make gnattools/gnatlib build like other target tools/libraries.
Actually, I was going to try to convince y'all to allow the *configury* to be put in the *configure* files. All of it. The current scheme of stuffing the configury in the Makefile, although I know the Ada maintainers like it, is just trouble, and is fundamentally the source of most or all of the endless Ada cross-build problems. We could certainly create a file much like config.gcc in gcc, so that 'autoconf' doesn't need to be rerun, but 'configure' *should* need to be rerun to change configuration.
