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.

     5     ARM: reorder "Use BX" option

     6     

     7     "Use BX" is not available on all CPUs, so the option depends on

     8     a correct CPU to be chosen . It is weird that e BX" then appears

     9     _above_ the CPU selection, not below.

    10     

    11     Move the "Use BX" after the CPU selection.
