   Could you please add a new m68k-gnu target to the binutils? It's
   basically an elf target, like i386-gnu (without mach3 stuff) or

I patched bfd/config.bfd, gas/, and ld/configure.tgt for
m68k-gnu.  Sorry about the long delay.

   I would like to have REGISTER_PREFIX_OPTIONAL set for this target, but
   didn't figure out where it had to be put... I just put it in tc-m68k.h
   (as described below), but it's of course a stupid solution, which did
   the trick for what I had to do...

I don't understand why you want to make this change.  This is normally
the wrong thing to do for an m68k ELF target.  The macro only exists
for target with a lot of legacy m68k code which does not use register
prefixes, but presumably that is not the case for m68k-gnu.  The flag
should not normally be set when compiling C code, unless the compiler
has been modified to use leading underscores on symbol names;
otherwise, the flag can cause gas to misassemble C code which uses
function or global variables with names that happen to be the same as
m68k register names.
