cross-compiling 3.5.x to ARM

[Dallas Clement]

Hello All,

I seem to be having a difficult time getting any version of samba to
cross-compile to ARM.  I was able to build it natively just fine.  I am no
newb either when it comes to building and cross-compiling open source.  I
did configure for cross-compilation, and I do see that the cross-compiler is
getting invoked correctly.

I first tried 3.5.8.  It fails right away.

I then tried 3.5.0.  It makes a little more progress, but has other
problems.

I then decided to try 3.4.10.  It also failed with talloc linking errors:

...

Perhaps part of my problem is that I am building this on a X86_64 host.
Maybe that's just asking for trouble.

I'm surprised that I'm having this much trouble.  Would someone kindly give
me some basic tips on how to successfully cross-build this for ARM?  What is
the recipe?  I just need a bare bones samba.  no ldap or ads, etc.  I would
appreciate knowing what the dependencies are if any.

Thanks much,

Dallas
