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.

     1 This is a somewhat ordered TODO list:
     2 
     3 Recurring tasks:
     4 
     5 - update versions for every tools...
     6 
     7 - update and/or upgrade all samples
     8 
     9 
    10 Non-recurring tasks:
    11 
    12 - update newlib (for enhanced bare metal)
    13   - confirm existing implementation on targets other than AVR32
    14   - try to make it generic, will help for uClibc++
    15 
    16 - multilib
    17 
    18 - Cygwin target (needs newlib)
    19   - so we can build toolchains that generate code for Windows/Cygwin
    20 
    21 - Cygwin host
    22   - so we can build toolchains that run natively under Windows/Cygwin
    23 
    24 - mingw32 target
    25   - so we can build toolchains that generate code for Windows/Win32
    26 
    27 - mingw32 host
    28   - so we can build toolchains that run natively under Windows/Win32
    29     (without requiring Cygwin)
    30 
    31 - uClibc++
    32   - see newlib, above
    33 
    34 - uClinux
    35   - check whether we can use newlib under uClinux (?)
