Critical fix: SOURCES_TARGET used mxdev wrongly with -o (offline) option.

The offline option had a bug and was fixed in mxdev [#34](mxstack/mxdev#34) and released with mxdev>=5.
  This fix switches from `-o` to the correct `-f` (no fetch from vcs).
  To update your makefile use `mxmake update` in the folder with your `Makefile`.
