`makepkg` generates two packages

hi, when I run `makepkg`, it generates a second package with the `-debug` "extension" (eg. `mypackage-w.x.y-z-x86_64.pkg.tar.zst` and `mypackage-debug-w.x.y-z-x86_64.pkg.tar.zst`). I couldn't find anything about this on the wiki : is this a new feature and/or is there a parameter to pass to `makepkg` to avoid building it ? regards, lacsaP.
