Public bug reported:

We're currently planning to be more proactive in deprecating the
uselib() syscall similar to how we deprecated the sysctl() syscall. This
will be a long process of course but the starting point is to set
CONFIG_USELIB=n in all new Ubuntu versions. I spoke to Eric and
apparently RHEL 8 has it disabled too.

The regression potential is quite minimal as this interface should have
very few users and libc hasn't used it since libc4 or libc5.

I was wondering what people's opinion on this were.
