Great news!  I'm pretty sure you are the first person to have
cross-compiled Samba4, or if not, the first person to have done it in a
long time.  (The ability was there, but you know the difference between
theory and practice). 

Could you write up in the wiki what you needed to do, and if there are
any small changes we could make to the build system to make it easier
next time?
