The fourth argument to _FP_CMP is a 4-state integer operand that
controls the operation wrt raising exceptions. However, the usage
that we need within QEMU produces a -Werror=int-in-bool-context:
error: ?: using integer constants in boolean context, \
the expression will always evaluate to ‘true’
glue(FP_CMP_, FS)(r, A, B, float_relation_unordered, (quiet ? 1 : 2));
note: in definition of macro ‘_FP_CMP_CHECK_NAN’
if (ex) \

Adding an explicit comparison avoids this.
