    The same error fixed in commit b224637928e9fc04e3cef3e10d02ccf042d01584
    happens in the 32-bit implementation of memchr for power7.
    
    This patch adopts the same solution, with a minimal change: it
    implements a saturated addition where overflows sets the maximum pointer
    size to UINTPTR_MAX.
