Alternatively, you could recompile Blender yourself, it then works
with the platform Python. This is on my machine:

>>> import sip
>>> sip.__file__
'/usr/lib/python3/dist-packages/sip.cpython-34m-x86_64-linux-gnu.so'

However, that won't help your users if you want to distribute a binary
extension.

I don't know how much effort it would be to compile Blender with
multiarch-Python by default, and what kind of incompatibilities it
would give on other platforms/distributions. Maybe someone else can
comment on this?
