fix --no-debug-support configuration.

* debug.h (debug_init): Define as ((void) 0) macro in the
no debug support case.

* unwind.h (uw_last_form_expanded): No-debug-support version
must yield a value, not void.

* unwind.c (ffcal_frame_type, eval_frame_type, expand_frame_type):
Define only if CONFIG_DEBUG_SUPPORT is enabled, to suppress
unused warnings.

* eval.c (do_eval): Conditionally define debug-related code.
The uw_push_eval function doesn't exist if CONFIG_DEBUG_SUPPORT
isn't enabled.
