I think the bug is that everything uses debug=N.
Perhaps that variable should be controlled by the subsystems?
Like 'make debug_$subsys=N rpmbuild' which sets debug=N before the
'include $(XEN_ROOT)/Config.mk'.  Then configure --enable-debug will set
debug_$subsys in config/$subsys.mk which in turn sets debug=.
