#     kbuild: move -Wundef from KBUILD_CFLAGS to KBUILD_CPPFLAGS
#     
#     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.
#     
#     Fix some uncovered issues.
#     
#     [1] Add -D__LINUX_ARM_ARCH__=* to KBUILD_CPPFLAGS
