math-emu/soft-fp.h: (_FP_ROUND_ZERO) cast 0 to void to fix warning

[ Upstream commit 83312f1b7a ]

_FP_ROUND_ZERO is defined as 0 and used as a statemente in macro
_FP_ROUND. This generates "error: statement with no effect
[-Werror=unused-value]" from gcc. Defining _FP_ROUND_ZERO as (void)0 to
fix it.
