[src/trunk]: src/sys/arch/m68k/fpe avoid a GCC warning with this:

[mrg <mrg%NetBSD.org@localhost>]

description:
avoid a GCC warning with this:

+#if defined(__GNUC__) && (__GNUC__ >= 5) && defined(__OPTIMIZE__)
+       x.fp_sign = 0;
+#endif

(ridiculous, but seems better than disabling the warning entirely.)
