* 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.
