Your suggestion is fine in this sense. I can observe that the following command variant
works as expected here.

my_build_dir=/tmp/fixdep-check-20161018-1 && mkdir "${my_build_dir}" && my_cc=/usr/bin/gcc-6 && make O="${my_build_dir}" HOSTCC="${my_cc}" allmodconfig && make -j6 O="${my_build_dir}" HOSTCC="${my_cc}" drivers/md/

The command example above is an approximation for the configuration approach
which I would really want instead.

How do you think about to clarify further which implementation detail could trigger
the shown software build difficulty?

Can it be that the passing of the adjusted parameter "HOSTCFLAGS" has got a significant
influence (with unwanted side effects) in this use case?
