* configure.in, Makefile.am: Explicitly specify whether an
	RTEMS_CPU_MODEL is using old or new exception processing.  This
	is important because when building multilib, you do not know
	the RTEMS_CPU_MODEL.  So everything built in a multilib'ed RTEMS
	must be independent of the exception model and allow for late
	binding to the exception code.
