Require haswell as minimum instruction set.
This can be overriden with DEFAULT_VESPA_CPU_ARCH_FLAGS when running cmake.
- Require skylake: cmake -DDEFAULT_VESPA_CPU_ARCH_FLAGS="-march=skylake" .
- Require sandybridge: cmake -DDEFAULT_VESPA_CPU_ARCH_FLAGS="-march=skylake" .
Or any other cpu architecture supported by gcc.
