Patch

From b00d8fd645679b3899104f2b7f002a9258559c28 Mon Sep 17 00:00:00 2001

Subject: [PATCH v2] Properly run tst-spawn5 directly [BZ #28067]

Change tst-spawn5.c to handle tst-spawn5 without optional path to ld.so,
--library-path nor the library path when glibc is configured with
--enable-hardcoded-path-in-tests.  This fixes BZ #28067.
