Makefile: Disable "format-truncation" warning globally
This was introduced in GCC 7.x: https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wformat-truncation
This warning doesn't really make sense in the context of the kernel
because there is no way for the values it complains about to be cut
off. For example, it complains about a cpu int getting truncated,
when in reality it will never be over 7 for this device (octacore).
