You will need to dynamically link the common sublibrary, or the symbol
space will not be exported.

This is probably a bug in the way export symbol tables are handled
for static code where dynamic linking is supported, if you want to
examine the technicality.

Specifically, there is not a shared export list for statically linked
(but exported) symbols in objects which aren't shared.
