Slightly less safe, but you can also do the rm command Ralph gave,
followed by a "make -k", which will regenerate just that makefile,
then update the .deps files, then build the sources. You probably
want to do a plain-old make after that to make sure nothing failed in
the build, as Make will report an error occurred during "make -k".
