Subject: [PATCH] linux-user/main.c: Call cpu_exec_start/end on all target
 archs

The start_exclusive() infrastructure is used on all target
architectures, even if only to do the "stop all CPUs before
dumping core" in force_sig(), so be consistent and call
cpu_exec_start/end in the main loop of every target.
