Fix possible bug when no args have been provided to the executable
Hi, This bug is related to: <https://sourceware.org/ml/gdb-patches/2017-06/msg00216.html> On stringify_argv, we have to check if args[0] is not NULL before stringifying anything, otherwise we might do the wrong thing when trimming the "ret" string in the end. args[0] will be NULL when no arguments are passed to the inferior that will be started. Checked in as obvious. gdb/ChangeLog: 2017-06-08 Sergio Durigan Junior <sergiodj@redhat.com> * common/common-utils.c (stringify_argv): Check for "arg[0] != NULL".
