Same branch (contrib zedd/ppc-tune), now has:

--- a/meta/recipes-multimedia/flac/flac_1.2.1.bb
+++ b/meta/recipes-multimedia/flac/flac_1.2.1.bb

 PACKAGES += "libflac libflac++ liboggflac liboggflac++"
 FILES_${PN} = "${bindir}/*"

Everything else is the same.

Let me know if you want a full resend of the patch.

Cheers,
