sim: constify dup_arg_p
The dup_arg_p function is only given const strings, and it maintains a local table of those const strings. So constify the whole thing to fix the GCC warnings: common/sim-options.c: In function 'sim_parse_args': common/sim-options.c:559: warning: passing argument 1 of 'dup_arg_p' discards qualifiers from pointer target type common/sim-options.c: In function 'print_help': common/sim-options.c:675: warning: passing argument 1 of 'dup_arg_p' discards qualifiers from pointer target type Signed-off-by: Mike Frysinger <vapier@gentoo.org>
