Could you pull out the sources into a gypi file which sets them as a variable
and that way they can be shared by both gn and gyp.

Done.  (Specifically, pulled from variables within the main gyp file.)

Maybe better to do a TODO(GN) here (and remove the GN code) to make it obvious
that this needs to be added.

Done.
