[PATCH v0 1/4] git gui Makefile - remove Cygwin modiifications

[Mark Levedahl <mlevedahl@gmail.com>]

git-gui's Makefile hardcodes the absolute Windows path of git-gui's libraries
into git-gui, destroying the ability to package git-gui on one machine and
distribute to others. The intent is to do this only if a non-Cygwin Tcl/Tk is
installed, but the test for this is wrong with the unix/X11 Tcl/Tk shipped
since 2012. Also, Cygwin does not support a non-Cygwin Tcl/Tk.

The Cygwin git maintainer disables this code, so this code is definitely
not in use in the Cygwin distribution, and targets an untested /
unsupportable configuration.

The simplest approach is to just delete the Cygwin specific code as
stock Cygwin needs no special handling. Do so.
