Yann E. MORIN" 533e5c128c 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
