AVX2 is a "relatively" modern instruction set, only available in GCC since
2011 (released in 2012, GCC 4.7). Are you sure the libvpx buildsystem couldn't
cope with the absence of this option?
In any case, if your compiler doesn't accept -mavx2, then it's older than GCC
4.7 and is therefore not supported with Qt 5.7 and up. Upgrade.
