That message is actually from apk-tools, not abuild, and in this
particular case is misleading.  What abuild does is attach a
dependency set to a virtual package and then marks that virtual
package as a "world dependency".

Package dependencies themselves do not support tags, only "world
dependencies," but if you add just "go" to makedepends I believe it
will fall back to the @community repo.

In general though, community is not meant to be masked, the point of
using tags is to mask repos across versions, such as running a split
stable-edge setup, or ensuring that adding packages from the "testing"
repo requires explicit confirmation.  Either way, community should
normally be set up in the same way as main.
