Subject: [PATCH 2/2] math-emu/soft-fp.h: (_FP_ROUND_ZERO) cast 0 to void to fix warning

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

This modification references the content of glibc 'commit <In libc/:>
(8ed1e7d5894000c155acbd06f)'
