If the compiler does not recognise the specific CPU when building with the default "native" machine type, sse4.2 instructions can be missing, causing a build error. Rather than advising the user to change the machine type, we can just turn on SSE4.2 directly. This can prevent issues with running automated tests with older compilers/distros on newer hardware.
