If --with-gtk passes configure but does not build, it can only mean that
your system (pkg-config) is set up wrong.  We use 
pkg-config --libs|--cflags gtk+-2.0 in configure.in to find GTK, and those
command shall list all required includes and libraries as well.  If
pkg-config doesn't complain we must accept the output as is.  If it still
doesn't work, pkg-config is in error.

The fact that --with-x-toolkit=gtk and --with-gtk differs somewhat is
no big deal, especially if it can only be noticed with a badly configured
pkg-config.
