Hi,

config: mips-jz4740 (attached as .config)
compiler: mips-linux-gnu-gcc (Debian 5.3.1-8) 5.3.1 20160205
reproduce:
        wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross

        make.cross ARCH=mips 

Note: the linux-review/zengzhaoxiu-163-com/lib-GCD-add-binary-GCD-algorithm/20160428-195527 HEAD 35e1a24e8fc3a5308b053ed3c744f02ec2a76820 builds fine.
      It only hurts bisectibility.
