We currently always rebuild a package, even if it hasn't actually changed. This could be mitigated by figuring out a way to first run the pkgver() function without executing the rest of the PKGBUILD. With this information, we could send a HEAD request to the server (or maybe read the database) to check whether the package version is already present.

Running makepkg --nobuild --nodeps causes makepkg to download all sources & run the pkgver function, without actually starting the build. Makepkg also updates the PKGBUILD file with the new correct version. Because a PKGBUILD is just a Bash script, we could then source it & read the pkgver variable. To get the architecture, uname -m should suffice. With this info, we can send a HEAD request to the package file's endpoint to see whether it exists or not.
