Description: build: Set soabi for the combined shared library
 Currently the build for the combined shared library does not set
 any ABI version. Since this deviates from upstream we start with
 version 0.
 Probably it would be ok if upstream kept individual ABI versions
 for each individual library. Then the combined one would have to
 be incremented whenever any of those changes version.
 Though to me it would feel more logical if there would be only
 one ABI version for the whole set.
Forwarded: Not yet. Needs discussion about library versioning.
