Laurent Vivier 3e24bb3f12 linux-user: in poll(), if nfds is 0, pfd can be NULL ...

This problem appears with yum in Fedora 20 / PPC64 container.

test case:

    #include <stdio.h>
    #include <poll.h>

    int main(void)
    {
        int ret;

        ret = poll(NULL, 0, 1000);
        printf("%d\n", ret);
    }

target test environment: Fedora 20 / PPC64
host test environment: Ubuntu 14.0.2 / x86_64

original test result: -1

    13451 poll(0,0,1000,274886297496,268566664,268566648) = -1 errno=14 (Bad address)

patched test result: 0

    13536 poll(0,0,1000,274886297496,268566664,268566648) = 0
