commit: b7bc5eec71294f8df5db8a1e0be4c4eb09c007cd [139/148] libio: relocate pci io functions
config: x86_64-randconfig-i0-201706 (attached as .config)

reproduce:
        git checkout b7bc5eec71294f8df5db8a1e0be4c4eb09c007cd
        # save the attached .config to linux build tree
        make ARCH=x86_64 

Note: the hisi/topic-lpc-4.10-libio HEAD 06443d85dc35b64a704f7be84cc538281a1598f4 builds fine.
