Fangrui Song 21ac457f3f [ELF] Priorize the last catch-all pattern in version scripts ...

When there are multiple catch-all patterns (i.e. a single `*`), GNU ld and gold
select the last pattern. Match their behavior.

This change was inspired by a correction made by Michael Kerrisk to a blog post
I wrote at https://maskray.me/blog/2020-11-26-all-about-symbol-versioning ,
following the current lld rules.

Note: GNU ld prefers global: patterns to local: patterns, which might seem
awkward (https://www.airs.com/blog/archives/300). gold doesn't follow this
behavior, and we do not either.
