  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.

Fixes: a25a650be5f0 ("build: add infrastructure for meson and ninja builds")
