Merge r1432:1437 from /branches/newlib into /trunk :
- under bare-metal, the user is responsible for providing a gdbserver stub (r1433)
- install a CT_TARGET-cc -> CT_TARGET-gcc symlink for the core gcc (r1434)
- allow broader dependency in generated config files (r1435, r1436)
- prepare C library menuconfig for using a C library under bare-metal (r1437)

 # Bare metal config options

 config KERNEL_bare_metal

     select BARE_METAL

     help

       'Bare metal' refers to those programs that run without any kernel.

       You probably want to say 'y' here if you plan to use your compiler

       to build bootloaders. It is not yet suitable to build Linux kernels,

       though, because the APCI stuff relies on the target C library headers

       being available?!?!...
