That's probably because following your tip, i modified the 
striplibsfrommexfile.m file to rename the liboctinterp.so.[23] 
dependency from .so.1 or .so.2 to only .so, so i don't need to build and 
ship separate mex files for Octave-3 vs. Octave-4 although the required 
libraries are api/abi compatible.

Maybe your version of striplibsfrommexfile.m needs to carry a patch to 
avoid that rename?

It needs libasound.so the ALSA runtime library. I don't think it needs 
-utils, although those come in handy anyway for tweaking of ALSA for 
some use cases.
