Thanks, this patch is what I ([2] above) suspected was needed.

Note that HiPE never has used executable stacks, all this does is
annotate some assembly file modules so that the build tools don't
mark them as needing executable stack.

This will be included in the R13B release, extended to cover all
architectures not just amd64.
