into bsd.python.mk because this will affect *all* the ports, that define
USE_PYTHON in their Makefile's. I can't think a way how to (nicely) apply
USE_XZ to limited set of ports inside of bsd.python.mk. Using tar.xz
instead of .tgz in ${PYTHON_DISTFILE} will not work on systems, that lacks
xz in a base system and I dislike the duplication of USE_XZ internals in
bsd.python.mk for them.

in individual python ports. I did some test builds of python and it's
slaves (py-sqlite3, py-bdsdb, py-gdbm, py-tkinter) and everything seems
fine. I also diffed all the four pairs tgz/tar.xz of each python version -
and, as it was expected, their content is equal.

My suggestion is to do it :)

Thanks for doing the work.
