Adjust dependency rules to permit per-file flags
The dependency rules are currently done in a shell 'for' loop. This does not permit Makefile variables to adjust preprocessor flags as is done with normal compile flags, using the CFLAGS_path/file.o syntax. This change moves the dependency generation into the Makefile itself, and permits a CPPFLAGS_path/file.o to adjust preprocessor flags on a file or directory basis. The CPPFLAGS_... variable is also folded into CFLAGS during the build. Signed-off-by: Simon Glass <sjg@chromium.org>
