The RX floating-point hardware only works on 32-bit values so default gcc will build doubles as 32-bit, this make many test fail on RX build test. This commit force the build for RX arch to use 64-bit doubles FPU will be supported later on this arch Signed-off-by: Duy Nguyen <duy.nguyen.xa@renesas.com>
