Yes, I know. If you want to cross build with 4.x binaries, something
the project has never guaranteed would work with 5.x (or any cross
major release), then you need to create your own cross build world.
Otherwise, cross threading libraries like you've pointed out is doomed
to failure. It only kinda works now because you've not hit any of the
other landmines that await you in the major version bump of libc.so,
most of which people haven't bothered to document.
Maybe the project should help providing people with such cross build
environments, but today we don't. It would be a change that we'd need
to somehow integrate the infrastructure to support. That
infrastructure isn't there right now :-(.
