Ok, let me try it again. Here is my take. I know Ulrich may not agree
with me. To me, symbol versioning provides a way to reference and
define a symbol with a version. For a reference to the symbol "foo"
and version "ver1", it can only be resolved with the definition of
the symbol "foo" and version "ver1". There are 2 different versioned
definitions:

1. The normal versioned definition. The normal versioned definition of
the symbol "foo" and version "ver1" can only resolve the reference
to the symbol "foo" and version "ver1".
2. The default versioned definition. The default versioned definition
of the symbol "foo" and version "ver1" can resolve the reference
to the symbol "foo" and version "ver1" as well as the reference to
the symbol "foo" without any version. It can also be overriden by
another default versioned definition or a definition without version.

The symbol resolution should follow the normal ELF linker rule.
