Re: m68k - Dropping the Motorola syntax

The original m68k PIC generation was designed for Sun3/a.out, which only
worked with Sun as, not with GNU as, AFAIK.  This was using MIT syntax,
probably because Sun as does only grok that.  Now that support for Sun3
has been removed it would be possible to also remove support for non-ELF
PIC, so that PIC support is independent of the assembler dialect.
