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 Signed-off-by: "Yann E. MORIN" <yann.morin.1998@anciens.enib.fr>
