[vlc-devel] [PATCH] aarch64: Use ".arch armv8-a+feature" instead of ".arch_extension feature"

[Martin Storsjö]

Clang doesn't support the .arch_extension directive for aarch64 at
the moment, but the same effect can be achieved by using .arch
instead.

This is an alternative, much simpler, fix for this issue.

Posting the patch for reference for others, if nothing else.
