From: Victor Kaplansky <vict...@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".
