Yes. Something like a unlinked (virtual) library. Depending on it would not 
link that library but its object files. Shouldn't be that complicated but has 
its pitfalls: position independent code (PIC) is used for object going to a 
shared library but not for objects going to an executable or static library 
(unless you want to link the static library into a shared library).

OTOH: including the same objects into different libraries defeats the purpose 
of shared libraries.
