I'm also fine with posting the patches now, even though we know they're
targeted at the next release.

That said, maybe as a first patch, we can try and add the support for
building multiarch but with __riscv_v being defined so we don't need
the ifunc resolver?  That way, the previous memset patch and this
patch would be the full template for adding the rest of memcpy, etc.
functions?

I believe in the future, we going to see more distros building RVA23
as the base, so in those cases, the RVV ifunc isn't needed at all.
