Details:

Earlier I submitted a patch for bug #41236 that allowed the Mac to properly
link octave-gui to Qt when made available as a non-system framework.
Effectively, my patch required turning on the "---enable-link-all-deps"
whenever this scenario is encountered.

Unfortunately, this had the consequence that mkoctfile would link MEX/OCT
files to every Octave dependency. This makes distributing binary OCT/MEX files
difficult. On octave-maintainers, JWE agreed this should be fixed, so I have
sought a solution.

What I've done is create a new Automake variable AMCOND_LINK_GUI_DEPS that,
nominally, obtains the same value as AMCOND_LINK_ALL_DEPS. However, whenever
the above Qt scenario is encountered on a Mac, it is set to "true", even if
AMCOND_LINK_ALL_DEPS is "false". The downstream Makefiles related to the GUI
have been adjusted to include the GUI dependencies in the link list for
octave-gui if this scenario is encountered.

This is a much gentler solution to the previous problem, then. I've
successfully compiled on the Mac with this patch.
