No worries.  It's a very reasonable warning.  And it's only if you're 
testing with the latest binutils that it causes problems -- which is one 
of the goals of the tester -- to find this stuff when it happens, not 
6-12 months later.

Yea.  I saw that.  I ultimately decided against pruning as it would be 
useful to know if a test suddenly needs execstack.   That would 
generally be a sign of something gone horribly wrong.  I just (locally) 
added the magic to the rest of the affected tests and I'm testing it now.
