Cannot ignore 'make install' with automake

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.
