Subject: [PATCH] libftdi: do not force a build of python if !pythonSupport

libftdi has a `pythonSupport` parameter, but still produces a
(build-time) dependency on python even when it is set to `false`.
This commit corrects that.

This allows building tiny systems (think embedded widgets) that need
libftdi, without having to cross-build all of python for the target
system.
