FYI: I did the powerpc64 bulk build first and it had
no problems. As far as libffi goes, __int128 exists for
powerpc64. I'm not implying that __int128 should be
used for powerpc64.

I'll note that, depending on where/how float128 is
used,

typedef char float128[16] __attribute__((aligned(16)));

use as float128 might decay to a pointer in some contexts,
unlike what __float128 or __int128 would have done.
