Hi mudongliang,

[auto build test ERROR on: powerpc/next]
[also build test ERROR on: v4.3 next-20151105]

url:    https://github.com/0day-ci/linux/commits/mudongliang/uapi-elf-delete-unused-macros/20151105-234433
base:   https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git next
config: mips-jz4740 (attached as .config)
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
        # save the attached .config to linux build tree
        make.cross ARCH=mips
