This is necessary because WireGuard's latest handshakes parameter is returned in wallclock time, and if the system time isn't set, and the system is really fast, then this returns 0, which trips the test. Turning this on requires setting CONFIG_COMPAT_32BIT_TIME=y, as musl doesn't support settimeofday without it. Signed-off-by: Jason A.
