Note for package maintainers

cmake and make flag with AVX switch (USE_AVX in make and -DUSE_AVX=1 in cmake) was deprecated due to changes in code.
Disabling AESNI flag is no more required, required checks automaticaly will be done on code build stage.

Please update your build scripts according to changes.
