/* The e500 ABI says that either long doubles are 128 bits, or if
implemented in any other size, the compiler/linker should error out.
We have no emulation libraries for 128 bit long doubles, and I hate
the dozens of failures on the regression suite. So I'm breaking ABI
specifications, until I properly fix the emulation.
Enable these later.
