binutils: split binutils to backend/frontend, a-la cc_core

Move the actual binutils code to a backend function that builds the
required combo of build/host/target as requested by a frontend.

This split is currently a no-op, but is required for the upcoming
canadian-cross rework, where we'll be needing to build two binutils,
one for build/build/target, and one for build/host/target.

This applies to the three binutils:
- GNU binutils
- elf2flt
- sstrip

    25       The Embedded ABI (stack alignment of 8 bytes, etc).

    31       Add support for the Signal Processing Engine.  This will set up
    32       the toolchain so that it supports the SPE ABI extensions. This
    33       mainly targets Freescale e500 processors.
    34       
    35       Setting this option will append "spe" to the end of your target
    36       tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc
    37       configure/build system will know to include SPE ABI support. It
    38       will also automatically add "-mabi=spe -mspe" to your TARGET_CFLAGS,
    39       and "--enable-e500_double" to your CC_EXTRA_CONFIG_ARRAY, so you
    40       do not need to explicitly add them.
