Automake does not allow us to place the hooks before its generated actions, and does not allow us to check MAKECMDGOALS, and does not support a mechanism for disabling make install (such as noinst_SUBDIRS, requested a few times on automake mailing list). The only way I could preserve the current behavior is to have a GNUmakefile wrapper that will convert MAKECMDGOAL into a variable unknown to automake - which seems too convoluted a solution for the problem being solved. Hence the approach is to not override anything for --enable-local. It is now fully handled by selecting different values for CT_xxx_DIR in ct-ng.in; but at the build-system level, all the variables remain the same. We just don't support 'make install' in that case anymore; but the ct-ng in the working copy can be used after a regular 'make' (or 'make all'). Help message for --enable-local updated accordingly.
