We should look at the overhead of building with endian_reverse enabled vs not. I can't imagine that it's measurable, but we should see. If it is indeed negligible, we should just always build with endian_reverse enabled and get rid of the option. (I was going to leave this discussion for when I had some bigendian output files for the output_archive, but since this is relevant.)

Sorry for the fuss the original issue was already closed. I tuned this service to only report new issues.
