Try with the -MP option, rather than the -M option.

>From the gcc man page:

 -MP This option instructs CPP to add a phony target for each dependency
     other than the main file, causing each to depend on nothing. These
     dummy rules work around errors make gives if you remove header
     files without updating the Makefile to match.
