dependency file...
'-MF FILE'
When used with '-M' or '-MM', specifies a file to write the
dependencies to. If no '-MF' switch is given the preprocessor
sends the rules to the same place it would have sent preprocessed
output.
When used with the driver options '-MD' or '-MMD', '-MF' overrides
the default dependency output file.
it sends to *.o.d
but it seems to want *.d
