Chen Gang ee4f96d0f0 openrisc: Makefile: append "-D__linux__" to KBUILD_CFLAGS
Need append "_D__linux__" to KBUILD_CFLAGS, just like some of another
architectures have done, or 'allmodconfig' can not pass compiling.

The related error:

    CC [M]  fs/coda/psdev.o
  In file included from include/linux/coda.h:65:0,
                   from fs/coda/psdev.c:45:
  include/uapi/linux/coda.h:221:2: error: expected specifier-qualifier-list before 'u_quad_t'

The related compiler information:

  [root@dhcp122 ~]# /usr/local/bin/or32-linux-gcc -v
  Using built-in specs.
