Does the patch fail I submitted fail any compile tests?

AFAIK, it compiles but the resulting binary might just be rubbish on some 
boards.

It worked fine on my overo board without any changes to the overo lds.

I have just verified that it builds on
overo
mx51evk
davinci_sonata

If there is an expectation to build every possible config is there a script 
that will do that?

That was based on some observations a year or two ago. I don't know if the 
problem has now gone away and have no way of reproducing it.
