{CFLAGS,LDFLAGS}_MODULE are supposed to be set by users, not by in-kernel makefiles. Documentation/kbuild/makefiles.txt clearly explains the difference: KBUILD_CFLAGS_MODULE Options for $(CC) when building modules $(KBUILD_CFLAGS_MODULE) is used to add arch-specific options that are used for $(CC). From commandline CFLAGS_MODULE shall be used (see kbuild.txt). KBUILD_LDFLAGS_MODULE Options for $(LD) when linking modules $(KBUILD_LDFLAGS_MODULE) is used to add arch-specific options used when linking modules. This is often a linker script. From commandline LDFLAGS_MODULE shall be used (see kbuild.txt).
