Subject: * Makeconfig (+link-bounded, link-libc-bounded,
X-Git-Tag: cvs/glibc_2-1-92~75
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ac556388135e5bf0578cb24bc958870ff3a0f00c;p=platform%2Fupstream%2Fglibc.git

* 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.
