I don't think this has ever been a command line option in fsf gdb.
Maybe it is one that was added to Apple's version of gdb.

Try running `/Users/n179911/bin/gdb/bin/gdb --help', and
then run the same command using your installed gdb that came
with Mac OS.  My guess is that the Mac version will list
"--arch" among the command line options, but the fsf version
will not (mine doesn't).
