    sys/time: appease gcc -Wtype-limits
    
    In environments where time_t is 32 bits, including the 32-bit library
    build on amd64, the overflow being tested for cannot happen, and gcc
    complains with -Wtype-limits, causing the gcc build to fail.  Work
    around this by ifdef'ing out the saturation code on i386.
