Subject: [PATCH 2/3] hexagon: add KBUILD_ prefix to CFLAGS_MODULE, LDFLAGS_MODULE

{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).
