We follow the same approach that v3d. We compile the files that
depends on the version several times, passing a different version each
time. We link all those per-version libs on the main library.
Note that right now we only support version == 42, so the array of
supported versions is one-sized.
Also note that although we were doing a previous work to split
hw-version dependant code from general code, this is the first commit
that only inject the current V3D_VERSION on the former.
We have two cases where we hardcode the V3D_VERSION (as a full
wrapping would be an overkill) that we need to include here to avoid
warnings/errors if we do that before or after.
Having some exceptions also happens on v3d. As we are here we add some
comment on v3d clarifying that.
