On i386, Linux doesn't provide direct socket syscall but instead multiplexes them through the socketcall syscall (see `man 2 socketcall`). This commit fixes compilation for i386 by wrapping the offending syscall in a new function that uses the socketcall syscall on i386, and the `setsockopt` syscall on other archs.
