I tracked it down to incomplete target data for 128 bit floats: f128 wasn't
defined, which caused compilation errors. This uncovered a larger problem. The
ppc long double format isn't supported by APFloat.cpp. This makes things like
hex float constants fail. I'll think about it and figure out what to do
