Comment (by wolfgang):

 There is a flag for Apple's linker, -read_only_relocs suppress, which
 allows you to link bundles with non-position-independent code.
 Position-independent code is *not* strictly required to build a bundle or
 a dynamic library, but:

  * position-dependent bundles/libraries take slightly longer to load,
 because they have to be relocated at load-time
  * if more than one process uses the bundle/library, it has to be loaded
 into memory separately for each process, i.e. the "shared" library is not
 really "shared".

 On the other hand, position-independent code is slightly bigger and slower
 than position-dependent code (on most platforms, including powerpc and
 x86), so -fPIC was left off by default. Everyone, feel free to comment.
