Daniel Bertalan 4a428ba252 Meta: Do not allow undefined symbols in executables and shared objects
The `--allow-shlib-undefined` option is a bit of a misnomer. It actually
controls whether we should be allowed to have undefined references after
symbols from all dependencies have been resolved, so it applies both to
shared libraries and executables.

LLD defaults to allowing undefined references in shared libraries, but
not in executables. Previously, we had to disable this check for
executables too, as it caused a build failure due to the
LibC-LibPthread-libc++ and the LibCore-LibCrypto circular dependencies.

Now that those have been resolved, we can enable this warning, in the
hopes that it will prevent us from introducing circular libraries and
missing dependencies that might cause unexpected breakage.

About

SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.

You can watch videos of the system being developed on YouTube:
