Hi

There are some minor inconsistencies in the build system:
a) If --disable-{alsa,gstreamer} are given on configure LIBSBC doesn't
get built. Even though SBC_CFLAGS and SBC_LIBS get substituted in the
Makefile and therefore libsbc.la ends up in the link-list for libipc
which then fails.
b) ipctest needs libipc and libsbc but gets built unconditionally in
audio/Makefile.am.

The attached patch fixes that.

Cheers,
Tiziano
