Add 2011/richards try scripts

The bugs.md refers to the alt try script for testing any fix with the
Apple silicon chip. If someone gets it to work the entry could be
removed from the bugs.md file and the README.md file updated to refer to
the alternate code. As the alternate code does not work (though it has a
different type of crash) the alt build/try is not mentioned in the
README.md file. It is not clear if it's helpful or not to have it in the
README.md at this point as the important part is in bugs.md.
