Fix proxy script to place commands properly with ar. Proxy scripts append parameters from original command at the end of the command line. However, binutils ar util requires the command option to be passed as the second parameter. This patch checks for the command parameter and if present inserts it as the second option. Limitation: this patch only considers plain commands, not commands with options (a proper reg exp should be used).
