Oddly this fails with clang. E.g.

$ objdump -p bin/.mir_demo_client_basic-uninstalled | grep NEEDED | grep libmir | grep -v libmirclient
  NEEDED libmircommon.so.4
  NEEDED libmirprotobuf.so.0

It looks as though the clang linker creates empty entries for these in the .dynstr section:

$ readelf --string-dump=.dynstr bin/.mir_demo_client_basic-uninstalled
