Launching sysbench on a x86-64 machine without AVX results in a SIGILL crash due to a vxorpd instruction.

I've tried the versions in 20.09 and unstable, same result.

I just compiled sysbench original sources and it works fine. Could hydra be building with AVX enabled for all packages?

The upstream sources aren't using any -march/-mcpu/-mtune flag.

Wrong, there's indeed an upstream detection for the host CPU that, on some boxes, ends up using a -march=xxx flag. Passing --with-gcc-arch=uknown to configure seems to fix this problem.
