config: prepare for build-system backend

When acting as a backend for a build-system, we should not build
any application that runs on the target, that is:
- no native gdb
- no companion libraries
- no binutils libraries
- no debug tools (save for gdbserver)
- ...

Here, we simply prepare the (hidden) config option that will detect
that we are acting as a back-end.

Update doc accordingly. 
     1 # Dummy config file to not use a C library *at all*

     2 # depends on BARE_METAL

     4 config LIBC_none

     6       Do not use a C library.

     7       

     8       This is usefull if your project is self-contained, does not rely on

     9       an external C library, and provides all the necessary bits.

    10       

    11       Most probably usefull to bootloaders, as they generally don't depend

    12       on the C library.

    13       

    14       If unsure: do *not* choose that, and use another option in the choice.
