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.

     7 Attached is a patch to add __attribute__ ((noinline)) to

     8 call_gmon_start.

     9 

    10 Without this patch, the sec script that processed initfini.s removes a

    11 part of inlined call_gmon_start, causing undefined label errors.

    12 

    13 This patch solves the problem by forcing gcc not to inline

    14 call_gmon_start with __attribute__ ((noinline)).

    15 

    16 Tested by building for arm-none-lixux-gnueabi.  OK to apply?
