Comment 103 for bug 1711337

This is the freebsd patch from their bug report. It was generated against their ports tree, I edited it so that it can be applied against the firefox source tree instead. This is not an official patch, and it fixes freebsd only, but still it might be helpfull to see what they changed. It is confirmed to build at their ends with clang for armv6 + armv7

adding this just in case it might be helpfull at some point
