The recent libffi upload didn't build successfully on armhf, i386 and 
several -ports architectures. From the buildd log 
https://buildd.debian.org/status/fetch.php?pkg=libffi&arch=armhf&ver=3.7.1-1&stamp=1783944369&raw=0 
and other architectures:

Perhaps this means the affected architectures don't offer an int128 
type in their ABIs? They are mostly, but not entirely, 32-bit (sparc64 
is 64-bit).

If libffi is expected to need per-architecture symbols file adjustments, 
it might be a good idea to do the initial upload of each new upstream 
release to experimental, to avoid multiarch skew in unstable?

Thanks,

Appears to have been fixed by:

libffi (3.7.1-2) unstable; urgency=medium

   * Conditionalize new symbols on architectures.
