The method I use to create .d dependency files
automatically used to fail sometimes. To
diagnose the failures, I used a target like

.PHONY: check_empty_depends
check_empty_depends:
        @$(ECHO) Checking for zero-byte dependency files:
        @$(LS) --recursive --format=long ../bin/ \
          | $(GREP) '\.d' \
          | $(GREP) -w 0 \
          | $(WC) -l \
          | $(SED) 's/^/  /' \
          | $(SED) -e's/$$/ dependency file(s) defective/'

I guess you could adapt that to remove the
zero-byte files, and then running make again
(after fixing the problem) would rebuild them.
