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     Rules.mak: Rearrange appending UCLIBC_EXTRA_CFLAGS to CFLAGS

     6     

     7     UCLIBC_EXTRA_CFLAGS is currently added before the OPTIMIZATION flags

     8     and OPTIMIZATION is chosen to be Os by default. But in OE we pass the optimisation

     9     flags through UCLIBC_EXTRA_CFLAGS but they are not effective since -Os is

    10     specified at last. So we need to change the order of these option flags
