[Qemu-devel] [PATCH v2 3/4] vl.c: Guard against GThread double-initialization

["Andreas Färber" <andreas.faerber@web.de>]

GThread-ERROR **: GThread system may only be initialized once.
aborting...

Making the g_thread_init() call in vl.c conditional resolves an abort on
Mac OS X, where coroutine-gthread.c seems to call it before vl.c.
