The compiler may be configured by default to use a newer microarchitecture level such as x86-64-v3. Set purgatory to compile using the baseline x86-64 level since the environment isn't set up correctly to use SSE and AVX instructions. At the same time, be a bit paranoid and add some additional flags to ensure that the compiler doesn't use any such instructions.
