The relocation mechanism is used for either pic or non-pic code. If parts of your code reside in different compilation units (.c files), there need to be a way to tell the linker how to jump from one to the other, even if the final program will be run at a well-known static position in the address space. Of course, when compiling -fpic versus -fno-pic, different types of relocation information will be produced, and the compiler might produce different instructions for branching. And unresolved symbols will remain in your library to be fixed up by the dynamic linker. But relocation entries will be produced for either case.
