Well that narrowed it down quickly. I commented out the abort() calls
so all the tests would run, and commented out the alternate locale
testing because we don't install locales on our boxes. I'm also adding
-fno-builtin to the test compiles now.
Everything relating to printing a long double fails. I don't know yet
whether it's just printing, or whether all the failures at this point
are being caused by wrong or incomplete long double support in my
environment.
