m68k compile issue with 4.0.5

[Waldemar Brodkorb <wbx@openadk.org>]

Hi,

I am trying to build a M68K (Coldfire no-MMU) kernel for Qemu-system-m68k.

With 4.0.4 everything is fine. With 4.0.5 I get following compile
error:

cc1: some warnings being treated as errors

Any idea what change breaks the compile?
