Subject: [PATCH 3/3] c6x: add KBUILD_ prefix to CFLAGS_MODULE

CFLAGS_MODULE is 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).
