PATCH: Build csu/bcrt1.o only if build-bounded=yes

[Greg McGary]

I decided to punt on building BP startup files unconditionally.  BP
startup files currently require `-fbounded-pointers' (which wasn't
being passed because defining CPPFLAGS-.ob depends on
build-bounded=yes), but that's not available in any production gcc.
For now, it's best to just leave out all BP stuff unless someone
asks for it.

2000-07-03  Greg McGary  <greg@mcgary.org>

	* csu/Makefile (extra-objs, install-lib): Add BP objects conditionally.
	($(objpfx)b$(start-installed-name)): Add non-elf rule.
