Revert previous at the moment.

This is wrong reasoning; 68020 and above (incl. 040 and 060) support
32-bit displacements for PC relative addressing (via "fully extension
addressing mode" with null index register).

I've still not figured out what goes wrong with amiga/boot(8) when
compiled without -l option for gas(1)...
