Which version of GNU Radio are you running? This looks like an older
style of Makefile. Also, it looks like you've mixed in a bunch of
things into the Python directory that don't need to be there. If you
work from the latest git (master branch), you should make sure that
you can build and make check the gr-howto-write-a-block that's already
there and then start changing things.
