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.
