[poky] Extending SDK

[Gary Thomas]

I've built meta-toolchain-sdk and although it was saved in the
wrong place, all seems to be working well.  Until I tried to
build a program that uses some package which was not part of
the "default" set.   In particular, I tried to build 'xeyes'
outside of Poky using the SDK, but it needs xt and xmu libraries
which are built for my target, but weren't in the SDK I built.

Questions:
   * Did I miss something in building the SDK that left these out?
   * Is there a way, hopefully straight forward, of adding additonal
     packages to the SDK?  Can this be done incrementally, i.e. I
     already have an SDK installed, can I do some magic to just add
     the xt support?

I looked through the handbook, but didn't find much information
on this.

Thanks for any pointers
