fix ffmpeg build on osx i386

gcc 4.2 on osx defines the built-in macro __PIC__ which ffmpeg's configure
uses to determine if it should enable pic.  Enabling pic uses extra
registers which causes some inline asm to fail due to lack of available
registers.

I disabled the normal check and forced pic enabled for x86_64 since it
requires it.
