Build failure on PowerPC and PowerPC64.

I updated to TOT today and now get the following on ppc and ppc64:

Making all in c/

All the other targets I tried workd (arm, i386, mips, microblaze, x86_64).

Anyone have a hint about what might be going on?

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
tomorrow.
