include/fpu/softfloat: Fix compilation with Clang on s390x
Clang v7.0.1 does not like the __int128 variable type for inline
assembly on s390x:
In file included from fpu/softfloat.c:97:
include/fpu/softfloat-macros.h:647:9: error: inline asm error:
This value type register class is not natively supported!
asm("dlgr %0, %1" : "+r"(n) : "r"(d));
^
Disable this code part there now when compiling with Clang, so that
the generic code gets used instead.
