commit: 39a54101d1cc581dbf494b0964537e795466e0d4 [6/14] target: Convert se_cmd->execute_cmd to target_iostate
config: sh-allyesconfig (attached as .config)
compiler: sh4-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

        # save the attached .config to linux build tree

Note: the target/queue HEAD 4d13930836b3a61c70603178d8a3c60e633e40f1 builds fine.
