libc/newlib: add a config option allowing to disable builtin syscalls

Allows to choose if one wants to keep or not the syscalls that are provided with
newlib. It passes the --disable-newlib-supplied-syscalls or
--enable-newlib-supplied-syscalls to the configure script. If one chooses to
disable the builtin syscalls, he/she will have to write his/her own. This can
be usefull to port newlib to a new platform/board.

    33       Disable the syscalls that come with newlib. You

    34 	  will have to implement your own _sbrk, _read,

    35 	  _write... If you plan to port newlib to a new

    36 	  platform/board, say Yes.
