since the SAMR21 Xplained has an ARM Cortex, it already uses newlib as it's
clib.
Just include <errno.h>. Documentation of the values you can find in the
manpages at errno(3) [1], but please do *not* use it as the errno in Linux
(setting the global constant `errno`) but just as the negative return value
of your functions, since `errno` is not thread-safe.

Cheers,
Martine
