As if developing #KF on an old #Core2Duo laptop wasn't bad enough (over 30minutes to build, have to use -j1 due to insufficient RAMs), it crashes with #SIGILL #IllegalInstruction on #vmovups which seems to be an #AVX instruction (CPU is so old it does not support it).

Retrying the build with `-march=native`, but I recall submitting a #GCC patch to #Debian to replace #aligned moves with #unaligned ones, so maybe I broke it all by myself (the stack on #Windows is only 16byte aligned...).
