PATCH: BPs in Makeconfig & Makerules

[Greg McGary]

2000-06-07  Greg McGary  <greg@mcgary.org>

	* Makeconfig (CPPFLAGS-.ob): pass -fbounded-pointers
	for all files *.[cS].  (CFLAGS-.ob): Don't optimize sibling calls.
	(bppfx): New variable.
	* Makerules (elide-bp-thunks): New variable.
	(elide-routines.*): Elide BP-* files for all but *.ob.
	(sources): Include bp-thunks.
