The biggest clarify problem I've seen is the terms being intermingled.  There 
are clear definitions for each.

Toolchain, the compiler and related tools that enable compiling software for a 
given target.

SDK - Software Development Kit - On OE-Core this purpose of this is to enable 
developing software to be run on a specific target environment, generally also 
constructed from OE-Core.  The SDK consists of three primary components:
   1) environment setup files - these configure the compilation environment with 
the right settings
   2) nativesdk software - these are applications that run on the -host- system 
to assist in compiling software for the target (this includes the target toolchain.)
   3) target sysroot - The sysroot is the collection of libraries, headers and 
assorted items that are compiled for the target.  A sysroot is setup in a 
similar fashion as a target's root filesystem.

ADT - Application Developer Tool - This is an Eclipse component that can use the 
SDK, generated by OE-Core, to enable application development within the Eclipse 
framework.  (I may be slightly wrong on this item, as people have told me in the 
past there are command line parts to the ADT.... but the ADT itself is -not- the 
SDK.)
