Bug#474891: reassign to libsdl-sound and ask for rebuild

[Evgeni Golov]

reassign 474891 libsdl-sound1.2-dev
retitle 474891 please rebuild libsdl-sound1.2 against new libspeex
thanks

libspeex currently droped it .la file (/usr/lib/libspeex.la) which is
still listed in /usr/lib/libSDL_sound.la. This leads to an FTBFS of our
package asc in unstable, as it cannot open libspeex.la during linking.
Locally rebuilding libsdl-sound makes libSDL_sound.la list -lspeex
instead of libspeex.la and asc can be build fine again.
A binNMU on all arches should be sufficient, however people have
suggested to drop .la files at all and stop libtool from doing
strange things :)
