[yocto] Python module not found when using autotools

[Serkan Türker]

Hi Alexander,

thank you for the quick reply. Doing the ./configure part on the host
machine for host (basically, compiling tizonia on Ubuntu) works fine, there
it can find the soundcloud module. I just don't understand where autotools
(during bitbake) is looking for the soundcloud module and what I have to do
to make it work.

Cheers,
Serkan
