This looks like it's expecting C++ linkage, but it's a C library. It
shouldn't have the complete prototype for the function for a C library.

Sure enough, this isn't a bug in libgsm.
#ifdef HAVE_GSM
#include <gsm/gsm.h>
#else
#include "gsm/inc/gsm.h"
#endif
this is the code in audio_encoder.h, and the HAVE_GSM check is failing --
which means the build is using a local copy of gsm in the src/audio/gsm
directory (bad) and the build is failing as a result (good :).
I don't know yet why this define isn't propagating; it seems to be part of
debian/patches/libgsm.patch though, and there's probably a race condition in
the autotools handling that's preventing it from getting where it needs to
be. In a rebuild test on amd64, config.log looks right to me, yet it's not
*consistently* ending up in the generated src/twinkle_config.h, because
there's a race condition with whether src/twinkle_config.h gets regenerated
after autoheader is run.
