binutils/binultils: import binutils-2.20 patches from OE

This is a set of patches for binutils-2.20 that have been "ported", or rather
shamelessly stolen, from the OpenEmbedded project:

http://cgit.openembedded.org/cgit.cgi/openembedded/tree/recipes/binutils/binutils-2.20

Tried and tested on Arm (big-endian Xscale, and little-endian i.MX27) with GCC 4.4.2

Signed-off-by: Joachim Nilsson <jocke@vmlinux.org>

# Compute s390-specific values

CT_DoArchTupleValues() {

    # That's the only thing to override

    if [ "${CT_ARCH_64}" = "y" ]; then

        CT_TARGET_ARCH="s390x"

    fi

}
