Subject: linux-user: Treat --foo options the same as -foo
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ba02577cadbe5b53db791522310c977f9960f81f;p=qemu.git

linux-user: Treat --foo options the same as -foo

The system mode binaries provide a similar alias
and it makes common options like --version and --help
work as expected.
