Makefile.inc: Explicitly set GNU11 as C language standard
Different compiler versions use a different C language standard by
default.
GCC 4.9 uses GNU89 by default [1], while GCC 5.x uses GNU11 [2].
The discussion on the mailing list in thread *[RFC] Setting C99 by
default* [3] resulted in the preference of C11, which results in build
errors.
So explicitly set it to GNU11, which is also what the current coreboot
toolchain with GCC 5.3 is using.
