As pointed out by Arnd this is due to there being two symbols that
control the gelic_udbg.c code.
I don't see the need for PS3GELIC_UDBG, without PPC_EARLY_DEBUG_PS3GELIC
it just causes gelic_udbg.c to be built, but never called.
The diff below fixes the error AFAICS.
I can just fold it in if you're happy with that Arnd.
