Subject: [PATCH] Build+test bn_mp_set_double.c on more platforms
Not all platforms/environments/architectures that support enough of
IEEE 754 for the purposes of mp_set_double() actually support enough
to legitimately define __STDC_IEC_559__, so only relying on that is
too strict. Fixes https://github.com/libtom/libtommath/issues/159
