I think we need to backport the patch [1] to gcc 4.9.3 but we still need to add
an exception in the autobuilder until the nios2 toolchain is rebuild.

Can you test this patch please:
http://patchwork.ozlabs.org/patch/592357/

Since other version of gcc are not available for nios2, we don't need to
backport this patch.

Thanks for looking at nios2 build failure.

Best regards,
Romain
