* psim-bottom, psim-gdb-bottom, psim-shared, psim-top.in: Add ability
	to force psim configuration to include System V IPC devices even when
	the test does not appear to be multiprocessing. This is used by some
	RTEMS application developers for system simulation and could be used
	to simulate a framebuffer if a UNIX process mirrored the buffer.
