systemc: Disable systemc when using gcc versions older than 5.0.
These versions don't support the std::put_time function. Since versions
of gcc older than 5.0 aren't going to be supported at all in the fairly
near future, this should only be temporary. The number of people using
both systemc and older versions of gcc should be very small, or even
zero.
