Subject[PATCH] 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.
Target: or32-linux
Configured with: ../gcc-openrisc/configure --target=or32-linux --disable-nls --enable-languages=c --without-headers --disable-shared --disable-threads --enable-werror=no
Thread model: single
gcc version 4.5.1-or32-1.0rc1 (GCC)
