[PATCH] [sim,rx] Silence warning that turns into a build error

[Luis Machado <luis.machado@linaro.org>]

On a 32-bit build, I ran into the following:

sim/rx/fpu.c:789:6: error: ‘*((void *)&a+8)’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
rv = fp_implode (&a);

To silence this, just initialize the struct with 0's.

sim/rx/ChangeLog:

YYYY-MM-DD  Luis Machado  <luis.machado@linaro.org>

	* fpu.c (rxfp_itof): Initialize structure.
