Teach Makefile to check header dependencies

Add a target to use the gcc-generated makefile snippets for
dependencies on header files to check the hard-coded dependencies.

With this patch applied, if any dependencies are missing, then

make clean
make COMPUTE_HEADER_DEPENDENCIES=YesPlease
make CHECK_HEADER_DEPENDENCIES=YesPlease

will produce an error message like the following:

CHECK fast-import.o
missing dependencies: exec_cmd.h
make: *** [fast-import.o] Error 1
