 Argument 3 will be $($(PKG)_MIRROR) in all calls, so there is no need to
make it an argument.  Just use $($(PKG)_MIRROR) directly, like it is done
for $($(PKG)_SITE_METHOD).

 You can easily support $($(PKG)_MIRRORS) (plural) with
for mirror in $($(PKG)_MIRRORS); do \
... $$mirror ...
done

 This will simply skip the loop if $(3) is empty.

 Is there a need to check for $($(PKG)_SITE_METHOD) at all?  This is not
done for the BR2_BACKUP_SITE after all.

 Err... Either it is a sourceforge package and then this will already be the
normal URL, or it is not and then this will just fail.  Or am I missing
something?
