Subject: [PATCH] process.c: fix rb_spawn_process() for nommu

rb_spawn_process() in process.c tries different solutions for when fork
and/or spawnv are/aren't available.
The last resort when both aren't is to use the system() call which
stores the value in the status variable, which isn't declared.
