We've had a couple of bug reports involving musl.  One recent.  I think they 
were on Alpine Linux, so I setup a box to see what would happen.

I've got things setup so it builds, but it doesn't run.  Is anybody actually 
running ntpsec on Alpine Linux?

Anybody recognize this?

Note that there is none of our code on the stack.
