The header tests track whether headers have been checked using empty *.hdrtest files in the build tree. This pollutes the build directories, as the files live in the same "name space" as the real output files, messing with TAB completion among other things. Hide the disgusting turds by placing them in .hdrtest subdirectories. Change the quiet command output to simply $< instead of trying to decode roughly the same from the increasingly complicated $@. Note that it would be somewhat nicer to have the basename of the .hdrtest files be dot-prefixed instead of using subdirectories. However, it's challenging to come up with a pattern rule for that, as we can list headers to test in the subdirectories of $(src) too, without requiring Makefiles and kbuild to descend to each of them.
