bug#25034: red-eclipse: "data" directory in "$out/", not in "$out/share"

[Adonay Felipe Nogueira <adfeno@hyperbola.info>]

It turns out that I couldn't figure out how to do so.

So far I have tried:

- Attempt 1

  - Add the output path as "prefix" variable to #:make-flags.

    But I don't think this will work because $(prefix) seems hard-coded
    in "src/system-install.mk".

- Attempt 2

  - Change "copy-paths" phase to:

    - Make "$out/share/redeclipse" directory.

    - Copy "data" to "$out/share/redeclipse/data".

    - Make "$out/lib/redeclipse" directory.

    - Make symbolic link from "$out/share/redeclipse/data" to
      "$out/lib/redeclipse/data".

  - Add "set-prefix-path" phase after "unpack" phase. With outputs as
    key:

    - Inside "src/system-install.mk", substitute:

      - Line begining with "prefix=", with "prefix=$out". The regular
        expression used for this was "(^prefix=)[^\r\n]*", this makes
        sure that the "prefix=" assignment is in it's own line.

In any attempt, Red Eclipse still complains that no "data" was found,
although it always builds successfully.

Any ideas? :)
