Most tests just test if it compiles.  AFAIK only the REGPARAM_BUG test
checks if it runs.  We can test for that.  But this is a bug not just
related to the AMD64, it is also the case when cross-compiling, I
think?  So this bug already exists, this is just one scenario that
triggers this bug, right?

I am not sure about that yet.

I will check in my patch later this evening.  After that I will have a
look at the REGPARAM issue.  I will try to test if it will build on a
system without 32 bits libraries installed.
