--- Comment #1 from Alan Modra <amodra at gmail dot com> ---
This will very likely not be fixed by any of the maintainers who look at this
bugzilla.  The difficulty is that -m needs to be parsed early
(ldmain.c:get_emulation) in order to choose the linker "emulation", part of
which is the set of extra options valid for that emulation.  That means that it
will always be possible to construct a linker command line that has ambiguous
parsing, even if we try to make the initial search for a -m option more clever.
 So a perfect solution is likely impossible, and it is likely that no one
actually wants to call an output file "-main".

Now if you, the reporter, feel that this bug ought to be fixed, I encourage you
to submit a patch to binutils@sourceware.org.  The solution should be something
along the lines of moving get_emulation to lexsup.c and rewriting it to use
getopt with the basic set of options.  You'd need to be careful to prevent
getopt permuting argv.  See the getopt man page.
