The reason is that some (deprecated) symbols where removed in libvpx-1.5.0 [0].
libav itself was updated to adapt to this in [1], but this commit is only in the master branch and chances are it never hits a 11.x release.

[1] https://git.libav.org/?p=libav.git;a=commit;h=4d05e9392f84702e3c833efa86e84c7f1cf5f612

Temporary workaround:
---------------------
Downgrade to libvpx-1.4.0 and mask it to not get updated again.

Possible solutions:
-------------------
1) restrict dependency on libvpx to <=libvpx-1.4.0

2) Apply the patch [1 (see above)] of libav in the src_prepare phase.

Way 2) would be preferred over 1), because libvpx-1.5.0 also fixed some bugs.

Strange,... waiting a week and recompiling solved the problem.
So this report can be considered solved.

For reference: This seems to be related to bug #565696.
