[yocto] python tkinter dependencies

[Jate S]

The python-tkinter module requires _tkinter. A result from a websearch
suggested that I needed to make sure tk (from meta-oe/meta-oe) and tcl
were installed before compiling python.

I added a DEPENDS on the tk and tcl recipes to both python and
python-tkinter in a python_2.7.3.bbappend. It did not work and was
never built.

I'm looking for tips to figure out what is going on. Thanks.
