cc/gcc: add the backend/frontend infra for final gcc

Currently, we issue the bare-metal compiler from the pass_1 & pass_2
core compilers, because the final gcc breaks while doing so.

This implies we have to build some libces during the start_files step,
instead of the standard libc step. This is the case for newlib.

By adding a backend/frontend infra to the final gcc, we can abstract
what backend to call: the standard backend for non-bare-metal gcc,
and the core backend for bare-metal.

This patch is just an no-op, it just adds the final backend and
frontend without changing the way bare-metal is built, to come in a
subsequent patch.

     7 GCC 4.3 changed the location of some of the header files.  I don't

     8 understand why you'd be getting these errors while building GCC since

     9 it provides them.

    10 

    11 With regard to GLIBC, Roland checked in some changes so that the GLIBC

    12 build system could find the new locations of the GCC provided header

    13 files.
