Revision: 6657
          http://svn.sv.gnu.org/viewvc/?view=rev&root=qemu&revision=6657
Author:   blueswir1

Log Message:
-----------
Flush stdout after printing usage()

Fixes qemu-arm|grep cpu - with _exit() getting output from qemu --help
is a bit random. Since no atexit() handlers are registered for user mode
emulation, just use exit() instead.
