---------------------------
scons: Avoid implicit command dependencies

Work around a bug in scons that causes the param wrappers being
compiled twice. The easiest way for us to do so is to tell scons to
ignore implicit command dependencies.

Testing Done

So how does this work?  The link certainly describes the relevant bug, but it doesn't mention the solution used here.  (I can sort of piece it together, but it would be nice to have a link to something that actually discusses how this workaround addresses the bug.)

I suspect I am the only one annoyed by this...unless someone else feels the same I will discard the patch.

If this is what I think it is, it can be pretty annoying when running regressions. The param stuff swamps the console and its harder to find the regression results.

That is the one. On second invocation it rebuilds the params, only to conclude nothing else needs doing.

You have a pending review.
