The following error occurs when building dtc module:
CHK version_gen.h
CC libfdt/fdt.o
cc1: error: dtc: No such file or directory [-Werror]
cc1: all warnings being treated as errors
make[1]: *** [libfdt/fdt.o] Error 1
make: *** [subdir-dtc] Error 2
In rules.mak, "-I$(<D) -I$(@D)" was expanded to "-Idtc -I." when
building submodule dct. Due to the using of "-Wmissing-include-dirs,
a warning would be rarsed. To avoid it, add "-I$(<D) -I$(@D)" to
QEMU_INCLUDES instead of QEMU_CFLAGS so that QEMU_CFLAGS does not
contain the "-Idtc".

v1 -> v2:
* Fix it by adding "-I$(<D) -I$(@D)" to QEMU_INCLUDES instead of
QEMU_CFLAGS(thanks to Paolo Bonzini for correction)
