Issue #1584: Provide options to override default search paths for Tcl and Tk
when building _tkinter. configure has two new options; if used, both must
be specified:
./configure \
--with-tcltk-includes="-I/opt/local/include" \
--with-tcltk-libs="-L/opt/local/lib -ltcl8.5 -ltk8.5"
In addition, the options can be overridden with make:
make \
TCLTK_INCLUDES="-I/opt/local/include" \
TCLTK_LIBS="-L/opt/local/lib -ltcl8.6 -ltk8.6"
