I assume this is for the performance gains that can be seen by loading 
non-PIC code over PIC code.  However, this is not an option on x86_64.  
Dynamically loaded code must be compiled with PIC on pretty much every 
platform except 32-bit intel.

The bigger puzzle is why you could link against non-PIC code in shared 
objects on 32-bit x86.  (I know the answer, but it has no real merit).  
If you want things dynamically loadable, they must be PIC.
