From: Victor Kaplansky <victork@redhat.com>

The old rules.mak loads dependency .d files using include directive
with file glob pattern "*.d". This breaks the build when build tree has
left-over *.d files from another build.

This patch fixes this by
  - loading precise list of .d files made from *.o and *.mo.
  - specifying explicit list of required dependency info files for
     *.hex autogenerated sources.

Note that Makefile still includes some .d in root directory by including
"*.d".
