    What version of Linux are you using? SuSE Enterprise Linux 8, and Red
    Hat Enterprise Linux 3 both do not have symlinks for libs from /usr/lib
    to /lib. They use a different machanism:

        suse# cat /usr/lib/libc.so
            /* GNU ld script
               Use the shared library, but some functions are only in
               the static library, so try that secondarily. */
            GROUP ( /lib/libc.so.6 /usr/lib/libc_nonshared.a )

    A true benefit.
