I come across this situation from time to time, and I've had to just manually 
create an archive of PIC object files so that it can be linked into the shared 
library. Generally a PIC static library is usable in static executables as 
well, as long as *something* (e.g. libc) was dynamically linked (thus forcing 
the PLT or whatever dynamic init code to be present).
