Currently cloudooo does not compile with gcc 6.3 ( default gcc from current debian stable ) because of ffmpeg component:

    [CC] nestegg/halloc/src/halloc.c.o

 } max_align_t;
   ^~~~~~~~~~~
Makefile:104: recipe for target 'nestegg/halloc/src/halloc.c.o' failed

Because we don't use ffmpeg in cloudooo, I'm just temporarily removing it .
