If you configure alsa-lib to use python then it is linked
with -lpython2.4 in buildroot, so libpython seems neccessary.

If you configure alsa-lib without python support, then it is 
not neccessary.

If python is built by Buildroot, then alsa-lib configure will detect
this, and try to link with -lpythonX.X which would fail
since it would try -lpython2.5 and Buildroot uses python 2.4.5.

Maybe it is possible to build python but configure
alsa-lib to not use it. Have not tested that.

I have as mentioned before, added the fix to my tree, but
the PC halted early in the build last night, so it is not tested yet.
Will commit, as soon as it seems to work OK.
