Thanks for doing this.

Both patches look good to me (but note I'm not an opcodes maintainer).

>From the nit department:

- I'm not sure on coding standard on the bfd side, but on the gdb side
  you'd write "disassembler_options_cmp (...) == 0" instead of 
  !disassembler_options_cmp, since the return value isn't a boolean.

- Spurious leading space after TAB in the ChangeLog entry.

It's kind of a shame IMHO to fix bugs like these without adding
regression tests, to prevent regressions (and to prove it
works :-)).  Could something be easily added to
testsuite/binutils-all/arc/ perhaps?

Both ARM and Power test these FOR_EACH_DISASSEMBLER_OPTION-related paths
using GDB's testsuite.  Grep for "set disassembler-options" under
gdb/testsuite/gdb.arch/.  But IIUC, ARC doesn't support
"set disassembler-options" yet, right?

Thanks,
