[binutils-gdb] sim: use libiberty countargv in more places


https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=34fed69938f1296b62354b2a825b49602fe7af50

commit 34fed69938f1296b62354b2a825b49602fe7af50
Author: Mike Frysinger <vapier@gentoo.org>
Date:   Sun Jan 3 01:40:46 2016 -0500

    sim: use libiberty countargv in more places
    
    A bunch of places open code the countargv implementation, or outright
    duplicate it (as count_argc).  Replace all of those w/countargv.
