Subject: sim: options: add --version support
X-Git-Tag: users/hjl/linux/release/2.25.51.0.2~2^2~14^2~34
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a542beff945c1a416f85309d57b21d4a18422883;p=thirdparty%2Fbinutils-gdb.git

sim: options: add --version support

The old run frontend had a --version option, but the new common
sim-options file does not.  Restore support for that so we can
get version info out of `run` when using the new frontend.
