Update gdbtk dependencies to fix --disable-gdbtk

[Daniel Jacobowitz <drow@false.org>]

I accidentally used cvs up -dP on one of my build trees last night, and a
whole bunch of my GDB scripts fell down.  I had bits designed to fix most of
this, but they didn't work well enough.

This patch addresses the only bit that completely failed outside of various
forgotten --disable-gdbtk options.  First of all, with that specified,
install-gdb depended on install-libgui but all-gdb did not depend on
all-libgui, so install-libgui failed.  Secondly, tcl/tk/itcl were still
configured and eventually built (by their install rules).

This patch makes --disable-gdbtk _really_ disable GDB's dependencies on TCL,
TK, itcl, and libgui.  Tested in a couple of cross configurations.  OK?
