I see two possible ways around this:

 - Have two separate variables, like <pkg>_EXTRA_SOURCE (to be used for
   perl, contains real source code that needs to be saved during
   legal-info), and <pkg>_EXTRA_DOWNLOADS (to be used for external
   toolchains).

 - Just like you don't copy <pkg>_SOURCE to legal-info when
   <pkg>_ACTUAL_SOURCE is defined, don't copy <pkg>_EXTRA_DOWNLOADS
   when <pkg>_ACTUAL_SOURCE is defined.
