Don't we have to verify it at ppc64 as well? CC'd to debian-ppc.

According to [0] I created svn version 2249 on alioth [1]. I've tested
it on amd64, were rc4 symbols appeared by checking via readelf. But
maybe alsa-devel rechecks the buildsystem of alsa-libs to avoid that
dirty hacks? --with-versioned appended to ./configure opts didn't

Jordi, please recheck and upload.
