The official packages are built in a clean container with the makepkg configuration files in the devtools package. In the past, portability issue would have been a factor. I do think the status quo of having it match the devtools flags is perfectly fine, as it's trivial to replace `-march=x86_64 -mtune=generic` with `-march=native`.
