Actually, I read over this a little too quickly, and I realize now
you're referencing an OpenAFS file for this information (I thought this
was coming from a system include file or something). That is quite old;
I'm not really sure if that's true anymore. Something you can try pretty
quickly is to just get rid of that #undef, and the build should try to
use ucontext (unless there's something else disabling it elsewhere, but
I wouldn't think so).

It looks like glibc does have a getcontext/makecontext for aarch64, but
I'm not looking into this deeply at the moment. I can verify later or
someone else can speak up, but you can also just try it and see if it
works :)
