# Beware: cpudetection aka fat binaries only works on x86/amd64
# When we enable more cpus we will have to carefully filter.

# FIXME: In the same way there was QA regarding executable stacks
# with GMP we have some here as well. We cannot apply the
# GMP solution as yasm is used, at least on x64/amd64.
# Furthermore we are able to patch config.ac.
