Textifying the numbers is not the problem, there's already the ldtoa
functionality.  Missing the set of long double functions is.  I think
it's not the GLIBCXX_HAVE_BROKEN_VSWPRINTF, but the _GLIBCXX_USE_C99
flag or something like that.  JonY?

It would still be nice if somebody with a bit of math knowledge would
contribute the missing long double functions to newlib.
