    arm64: arm_tf: Do not build raw bl31.bin binary
    
    coreboot's build system picks up the BL31 image as an ELF from the ARM
    Trusted Firmware submodule and inserts it into CBFS. However, the
    generic 'bl31' build target we run in the ARM Trusted Firmware build
    system also generates a raw bl31.bin binary file.
    
    We don't need that binary, and with the recently added support for
    multiple non-contiguous program segments in BL31 it can grow close to
    4GB in size (by having one section mapped near the start and one near
    the end of the address space). To avoid clogging up people's hard drives
    with 4GB of zeroes, let's only build the target we actually need.
    
    BRANCH=gru
    BUG=chrome-os-partner:56314,chromium:661124
    TEST=FEATURES=noclean emerge-kevin coreboot, confirm that there's no
    giant build/3rdparty/arm-trusted-firmware/bl31.bin file left in the
    build artifacts, and that we still generate .d prerequisite files.
