I've built the code with this patch and I saw no further problems. Can
you please describe what you mean by " it will not be possible to pass
the TCK with the build" ?
It looks to me that it is just an optimization on s390 and powerpc (with
FPU). Other Architectures like arm or mips are treated the same way.

I haven't.
