Avoid specifying old symbol versions for compatibility, by just not specifying a version at all #14044

Apparently unversioned symbol references just bind to any random version found: https://stackoverflow.com/a/19364771

In theory, this can be used to avoid specifying (and using!) the oldest glibc symbols. (Possibly it might even enable using our binaries on non-glibc systems as well?)

Only problem is, I can't see a way to instruct ld to do this. The StackOverflow answer above solves it by building the target library without symbols, but so long as we're using Ubuntu-packaged libraries, we can't really do that for glibc.

At the very least, I guess this can be solved when we finally build our own libc from scratch, but it'd be nice to find a proper solution.

This is probably a dumb question, but just for clarity, what's a symptom (or possible symptom) of this problem?

The feature request didn't seem to attract much attention in the past. Also, the issue seems not important enough right now to keep it sitting around idle in the list of open issues.

Closing due to lack of interest. Pull requests with improvements are always welcome.
