[Bug target/25477] builtin functions should use $LDBL128 suffix on darwin when appropriate

Hm, for some reason the obvious approach from c#16 doesn't work:

The patch:

the testcase:

long double test(long double x)
{
        return sinl(x);
}

debug output:

library_name = sinl
PATCHING
 <identifier_node 0xb7c893a8 sinl$LDBL128>

But still:

test:
        pushl   %ebp
        movl    %esp, %ebp
        popl    %ebp
        jmp     sinl
