So for now I have suppressed the error using the following patch (which
I will keep in my fixes tree until some other fix is applied):
From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Date: Fri, 22 Jan 2016 13:24:57 +1100
Subject: [PATCH] next: suppress the building of all the sound codecs on PPC
for now
