kbuild: add -Wundef to KBUILD_CPPFLAGS for W=1 builds
The use of an undefined macro in an #if directive is warned, but only
in *.c files. No warning from other files such as *.S, *.lds.S.
Since -Wundef is a preprocessor-related warning, it should be added to
KBUILD_CPPFLAGS instead of KBUILD_CFLAGS.
My previous attempt [1] uncovered several issues. I could not finish
fixing them all.
This commit adds -Wundef to KBUILD_CPPFLAGS for W=1 builds in order to
block new breakages. (The kbuild test robot tests with W=1)
We can fix the warnings one by one. After fixing all of them, we can
make it default in the top Makefile, and remove -Wundef from
KBUILD_CFLAGS.
