Ubuntu enables GCC's stack protector by default (see https://wiki.ubuntu.com/Security/Features). This causes link errors like the following: ...undefined reference to `__stack_chk_fail' To avoid these errors, this patch adds the "-fno-stack-protector" flag to both the CFLAGS used by the Contiki build process and the CFLAGS used by the newlib build process.
