cc/gcc: allow CC_EXTRA_CONFIG_ARRAY on baremetal

The final bare-metal compiler is built using the core backend.
Currently the core uses the CC_CORE_EXTRA_CONFIG_ARRAY variable.

While this works as supposed to, this can leave the user puzzled
in the menuconfig, since all he can see is the core options, not
the final options.

Only show the core options if any of the core passes are needed,
and use the final options in the core-backend if we're issuing
the bare-metal compiler.

use final option in core backend if issuing the bare-metal compiler]

The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,
yann@1162
     6
you have to actually list out the multilibs you want or you will end up with
yann@1162
     7
just one when using targets like 'sh4-linux-gnu'.

The resulting toolchain can't even build a kernel as the kernel needs to build
yann@1162
    10
with the nofpu flag to be sure that no fpu ops are generated.

Here we restore the gcc-3.x behavior; the additional overhead of building all
yann@1162
    13
of these multilibs by default is negligible.
