S390: Fix _FPU_SETCW/GETCW when compiling with Clang [BZ #30130]
The _FPU_SETCW and _FPU_GETCW macros are defined with inline assemblies. They use the sfpc and efpc instructions, respectively. But both contain a spurious second operand that leads to a compile error with Clang. Removing this operand works both with gcc/gas (since binutils 2.18) as well as with clang/llvm.
