I've just committed some changes that determine whether to use SWP
or LDREX/STREX at runtime using the info that Ben posted as a guide.
Perhaps if you have a RPi3, you could see if Otter works?

I think the pthread testing code may need some work to bring it up
to date, plus all the tests need to be built with the -static flag, but
that's proving difficult to achieve.
