I checked how GAS 2.x copes with the register prefix. Using the same
logic in an older version doesn't seem to be a straight forward change.

The AmigaOS/68k port uses MIT syntax because the AmigaOS/68k port is
a simple a.out port and thus doesn't need any special features. So
far GAS 1.x (with some enhancements) was sufficient and AFAICT, its
faster than a BFD-based version.
I would like to keep MIT syntax and maybe converting the MOTOROLA
define into a commandline switch.
