PATCH: makefile support for BP tests

[Greg McGary]

No build regressions.

OK?

2000-07-26  Greg McGary  <greg@mcgary.org>

	* Makeconfig (+link-bounded, link-libc-bounded,
	link-extra-libs-bounded): New variables.
	(built-program-cmd): Omit $(run-program-prefix) for static BP tests.
	* Makerules (do-tests-clean, common-mostlyclean): Remove BP test files.
	* Rules (tests-bp.out): New variable.
	(tests): Conditionally add BP tests.
	(binaries-bounded): Add variable and associated rule.
	* csu/Makefile [build-bounded] (extra-objs, install-lib):
	Move conditional stuff after place where condition is defined.
