If you had gone ahead with this patch, it would also have needed some
documentation, so that the macro could be found and used by future
programmers.

The disassembler currently allows arbitrary, target-specific flags on
the command line, prefixed by -m (or --disassembler-options).  You
could use these.  Alternatively if you want a permanent run-time
toggle, then an environment variable might be the way to go.
