Fwd: CMSG_LEN, CMSG_SPACE not there on illumos

Nevermind about CMSG_LEN, CMSG_SPACE being missing.
They're right there in sys/socket.h but only exposed if XPG4v2 or later,
so Samba needs to use -D_XOPEN_SOURCE=600

I took a stab a changing that, and ran into the "fun" of waf in
buildtools/wafsamba/wscript ...

I'll send my attempt at fixing this later...
