* 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.
