Building Binutils's GAS with a recent GCC (ie. 4.9.1) for --target=m68k-linux
fails due to a false warning, which aborts the build since -Werror is used.

Cf. Buildrobot build #351394
(http://toolchain.lug-owl.de/buildbot/show_build_details.php?id=351394):

--- Comment #2 from Segher Boessenkool <segher at gcc dot gnu.org> ---
I cannot reproduce this.  You have --enable-languages=c and it fails in java?
... Oh never mind, it needs checking=release to fail.  How strange.

Anyway: mine.
