I suppose the error only happens when building in a populated build tree
after updating the sources.  Starting off with a fresh build tree should
be fine, however.  Likewise I guess that just adding 'Makefile' as a
dependency to stamp-debug ought to work for incremental builds (haven't
tested that yet though).

Magnus is right that it would be cleaner to generate src/debug/Makefile
from config.status, but then the other modifications should be done from
there as well.  src/debug/Makefile is generated only if --enable-debug.

Cheers,
Ralf
