Я немного проверил. В libalsa не видно ничего такого, что должно
задевать ABI столь странным образом. В частности, файл src/Versions.in
не изменился.
$ git clone git://git.altlinux.org/gears/l/libalsa.git
$ cd libalsa

А результат сборки изменился очень странно. Было
GLOBAL DEFAULT 12 snd_pcm_hw_params_get_channels@ALSA_0.9
GLOBAL DEFAULT 12 snd_pcm_hw_params_get_channels@@ALSA_0.9.0rc4
Стало
WEAK DEFAULT 12 snd_pcm_hw_params_get_channels@@ALSA_0.9.0rc4
Заметь что дефолтного символа теперь нет, а тот который остался стал weak.
Там ещё много символов стало weak.
