[poky] Poky SDK as an external toolchain

[Gary Thomas]

Premise: I'm happy with the toolchain that builds with Poky/Yocto
Problem: I'm not happy rebuilding said toolchain all the time, nor
having my customers have to rebuild it.

Solution? I'd like to build the meta-toolchain and then be able to
use that as an external toolchain for subsequent builds.  That way,
I can create the tools and reuse them internally as well as pass
them to my customers.

How can I make this happen?  The last time I tried anything like
this, I spent many days in the attempt only to find out that it
was never going to work...

Note: sstate is *not* the answer.  Not only is it HUGE (well over
1GB for a typical setup), but it doesn't work reliably - see
bug #1536

Ideas/hints?

Thanks
