add new flags to output dependencies

Flags following gcc options: -M to output deps only, -MD to output
  deps while compiling (in .d files), -MP to output phony targets, -MG
  to keep missing copybooks, -MQ <target> to Makefile-quote target

Additional flags specific to GnuCOBOL: -fcopybook-deps outputs only
copybook names instead of file paths. -fcopybook-deps also forces -E.
