    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.
