Just a hunch, but does:

  git config --global pack.threads 1

help? The delta resolution is multi-threaded, but nothing else in the
clone should be.

Yes, `git config --global pack.threads 1` allowed things to continue.
The check-out was successful.

OK, that narrows it down. The question then is why threads don't work.
Is there something broken with threading or luck primitives on that
platform? Or are we doing something sketchy with concurrency that
happens to work on Intel but not elsewhere, and we end up in some kind
of deadlock?

I suspect if we want to know more, you'd need to use gdb to grab a
backtrace for each of the threads during the hang to see what they're
trying to do.
