sys-devel/gcc[gcj] has automagic dependency on media-libs/alsa-lib.

(In reply to Fabio Bonfante from comment #6) > Seems that the gcj flag require the 32 bit of > media-sound/jack-audio-connection-kit Things related to media-sound/jack-audio-connection-kit were described in bug #513578. Updated patches for 4 bugs are in bug #511832, whereon this bug (#513576) depends.
Let's close it as non-masked versions of gcc don't have gcj and related libraries.
