osutil: do not abort loading pure module just because libc has no recvmsg() On Solaris, recvmsg() is provided by libsocket.so. We could try hard to look for the library which provides 'recvmsg' symbol, but it would make little sense now since recvfds() won't work anyway on Solaris. So this patch just disables _recvmsg() on such platforms. Thanks to FUJIWARA Katsunori for spotting this problem.
