I want to clarify what I am proposing.
I would not be an entirely new architecture in the sense of i686, CPU extensions are not different architectures and shouldn't be treated as such.
What I would for us to do is to create a x86-64-axv2, etc. that would complement x86-64. We would not add it as a target for all packages, just for the ones that make sense.
For this pacman would have to support architecture priority. We could have something like this:
Architecture = x86-64-axv2 x86-64
This means if a x86-64-axv2 package is available, it would be selected over the x86-64 one. That way we don't need to rebuild all packages.
Where would you store this package? The pkgname must be unique in each repository database, so you would need a community-avx2 repository. Then it is as simple as Santiago said, just have users add the additional repository if they need it, giving it precedence in pacman.conf.
