Add minimal implementation of syscalls in retarget file.

The nonsys specification of the newlib library, supplied with the Arm
GNU toolchain provides stubbed version of several system calls, in
order to allow linking with libc. Amongst such subroutines are _fstat,
_getpid, _isatty ,_kill, _lseek, for which the GNU toolchain also
generates a linker warning.
Patch retargets these subroutines by adding a minimal implementation.
