It would disable the compile test, instead of allowing it to do its job.
powerpc_prefixed_addr and -mcpu=power10 imply float128 support is
available on the hardware, so ppc_float128_sw should be redundant. But
it isn't: IIRC it checks for runtime support, without disregarding the
warning, and as of a few days ago, it explicitly rejects vxworks
targets. So I'd prefer if this didn't go in, and the patch I proposed
went in instead.
