ldexp_881.c contains the following snippet:

        __asm ("fscalel %2,%1"
                : "=f" (temp)
                : "0" (value), "g" (exp));

fscalel is a floating point op, which obviously you're trying to

I'm wondering why that directory is even being visited, since almost all
the assembly files in there use floating point operations, which is
something you're trying to avoid.
