help?

Subject: [PATCH] Use ldconfig to generate sys_lib_dlsearch_path_spec.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Use ldconfig to generate sys_lib_dlsearch_path_spec so that internal library
search paths as well as all /etc/ld.so.conf and /etc/ld.so.conf.d/*.conf
entries are present.
