Ok, I reworked your (pretty complete and well done) implementation and renamed
the option to "--static-deps" to make it clear that it triggers a static build
(the name is still open to improvement). It's on the trunk now. Everyone who
can give it a try: please install a recent Cython and do so! Fixes and bug
reports are very welcome.

Since the main incentive for this change was to make it work under MacOS-X,
here's a big plea for Mac users to test this and suggest fixes!

I enabled the static build for other platforms than Windows, so I hope that it
still works under Windows. Another thing to test.

I still left the "make install" in, as it makes the integration with the rest
of the build process easier, which requires a working "xslt-config". That
could potentially be stripped out.

I changed the download directory to "libs" instead of "build/tmp" to allow
users to put their libraries there. However, this does not currently trigger a
static build without the "--static-deps" option. I'd like to see how people
use this first before enabling even more smartness.
