This commit rewrites fesetround and fegetround to set and get the
rounding mode in x86emu, and applies the rounding mode on rounding

Well I have a question. What is meant by "weak" for a symbol map? And in which situation should we use a weak map? |
Owner
This is a linker thing. That means the symbols can be overriden by one from another library basicaly. There is no simple way to know wich symbol is weak, you need to look at the original libs symbol for that. |

This PR rewrites fesetround and fegetround to set and get the rounding mode in x86emu, and applies the rounding mode on rounding functions (
{,l,ll}rint{,f,l}andnearbyint{,f,l}). Test24 (feround) can pass with this patch.The rounding mode can also be applied on other math functions if needed.
