Yes, this is intended. libffcall.so is a new library; per libtool rules [1]
it starts out with version 0:0:0, which on Linux translates to a .so.0.0.0
suffix.

The other three libraries have already been shipped as shared libraries by
some distros, as major version 0 (since no libtool versioning was used
in previous versions). Since the set of exported symbols of these libraries
have changed, they must now carry the major version 1.
