Further handle the lib64 -> lib symlinks.
It at least helps powerpc64 to build, and should innocuous to other archs.

     9 Hi,
    10 
    11 The appended patch fixes a typo in a low-level lock function.  It
    12 set the correct 3rd argument for the futex syscall in loop.  Sorry
    13 for missing such an embarrassing bug.
