Not sure: I don't like X on the servers ;)) But others can...

OK, I reworked the patch following the suggestion of Jakub and Johannes:
now configure has the built-in detection of the Tcl/Tk binary and has
the --with-tcltk/--without-tcltk options. To implement this I still
need the NO_TCLTK knob in the Makefile. Moreover, the configure's
switch --with-tcltk=/path/to/binary works as expected: the location
of the Tcl/Tk interpreter will be rewritten in the gitk and git-gui.
The patch follows on this thread.

And regarding the building troubles and the additional knob in the
Makefile: the trouble is in the packaging process. For example, RPM
or FreeBSD ports are looking at what is really installed, so if
user do not want the Tcl/Tk part, then no package parts that depend
on it should be installed. And the bare 'make install' installs all
things. Sure, you can make 'make install && rm -f <not needed
files>', but it is always a pain for the package builders to get
the idea about the precise file list. So I just wanted to integrate
the desired behaviour in the mainstream Git to make packager's life
a bit easy. May be by the cost of making developer's life a bit
harder: he should watch for the NO_TCLTK in his Makefiles.
