How does PKGBUILD target ARM?

[ericgundrum]

I've been exploring how to port the Arch Linux `git-annex` package to a Raspberry Pi 3. This seems as simple as adding 'armv7h' to the `arch` variable in PKGBUILD. (It seems `distcc` is a build dependency, too, but maybe that's just an artifact of building on ARM.) This approach seems to be working. At least, the build is running (probably for another hour).

While I wait, I've been examining a few alarm repo PKGBUILD scripts. So far none I've checked have `arch=('armv7h')`. This has me thinking that Arch Linux ARM normally makes ports in a different way, but I haven't found any documentation for that. Can anyone point me to an explanation?

Thanks.
