#     kbuild: avoid build error when single DTB is turned into composite DTB
#     
#     As commit afa974b77128 ("kbuild: add real-prereqs shorthand for
#     $(filter-out FORCE,$^)") explained, $(real-prereqs) is not just a list
#     of objects when linking a multi-object module. If a single-object module
#     is turned into a multi-object module, $^ (and therefore $(real-prereqs)
#     as well) contains header files recorded in the *.cmd file. Such headers
#     must be filtered out.
#     
#     Now that a DTB can be built either from a single source or multiple
#     source files, the same issue can occur.
#     
#     Consider the following scenario:
#     
#     First, foo.dtb is implemented as a single-blob device tree.
#     
#     The code looks something like this:
#     
#     [Sample Code 1]
#     
#       Makefile:
#     
#           dtb-y += foo.dtb
#     
#       foo.dts:
#     
#         #include <dt-bindings/gpio/gpio.h>
#         /dts-v1/;
#         / { };
#     
#     When it is compiled, .foo.dtb.cmd records that foo.dtb depends on
#     scripts/dtc/include-prefixes/dt-bindings/gpio/gpio.h.
#     
#     Later, foo.dtb is split into a base and an overlay. The code looks
#     something like this:
#     
#     [Sample Code 2]
#     
#       Makefile:
#     
#           dtb-y += foo.dtb
#           foo-dtbs := foo-base.dtb foo-addon.dtbo
#     
#       foo-base.dts:
#     
#         #include <dt-bindings/gpio/gpio.h>
#         /dts-v1/;
#         / { };
#     
#       foo-addon.dtso:
#     
#         /dts-v1/;
#         /plugin/;
#         / { };
#     
#     If you rebuild foo.dtb without 'make clean', you will get this error:
#     
#         Overlay 'scripts/dtc/include-prefixes/dt-bindings/gpio/gpio.h' is incomplete
#     
#     $(real-prereqs) contains not only foo-base.dtb and foo-addon.dtbo but
#     also scripts/dtc/include-prefixes/dt-bindings/gpio/gpio.h, which is
#     passed to scripts/dtc/fdtoverlay.
#
