the updated docker image is having problems with clang-3.7. It seems that
now the package process is adding *-fdebug-prefix-map* and that is not
supported in clang-3.7  
clang: error: unknown argument: '-fdebug-prefix-map=/code=.'
So I'm moving to clang-3.8 in the stretch version and to clang-3.9 in the
Push was made and docker images built has been triggered
Sorry for the noise,
