We have a lot of script-only packages that are universal for all arch-s
and those set PKGARCH:=all to indicate it.
Unfortunately, APK expects architecture to be set to "noarch" instead to
indicate that its universal so instead of having to update all packages
that set PKGARCH:=all and thus break OPKG lets simply translate "all" to
"noarch" when generating the APK package.
This will be required as soon we update APK to include [1] as it will start
enforcing package architecture checks.
