Not with libunwind itself.

You should be able to get that by walking the list of mapped objects.
You can get that with dl_iterate_phdr().  The callback will be invoked
once for each object and then you can check the ELF PHDR to see if the
IP falls inside the object.


PS: I'm cc'ing libunwind, since that's probably a more appropriate place
    to discuss such issues.
