* configure.ac, score/inline/rtems/score/thread.inl,
score/src/threaddispatch.c: Add ability for user to disable inlining
of _Thread_Enable_dispatch. This can save code space but more
importantly it means the binary generated does not have code inlined
that is difficult to test and very seldom executed.
