yes, this is to bypass it on PPC. the printf conversion functions don't work (at the moment) for IBM long double. if it is possible to fix them up using similar uint128 shenanigans that might be an option, but I am out of my depth.

would making this define conditionalized on IBM long double be acceptable? I assume a limited build is preferable to no build at all ;)
