content of build/tmp/work folder?

Hello everyone,

I am just starting to dive into Poky (and embedded linux). I really like
the concept and the idea of Yocto(resp. Poky) and up to now (almost)
everything worked as expected. But the build/tmp/work directory is puzzling
me.
The handbook stated "this directory contains various subdirectories for
each architecture". In m my working directory I found the following folders:

all-poky-linux
beagleboard-poky-linux-gnueabi
i686-nativesdk-pokysdk-linux
qemux86-poky-linux
armv5te-poky-linux-gnueabi
i586-poky-linux
i686-pokysdk-linux
armv7a-vfp-neon-poky-linux-gnueabi
i686-linux
qemuarm-poky-linux-gnueabi

Ok, beagleboard-poky-linux-gnueabi, qemuarm-poky-linux-gnueabi, ... are
architectures I build. But what about the others folders. What the meaning
of all-poky-linux?

A rough explanation would be very helpful.

"all" stands for all architectures, it contains stuff like python, perl, 
etc... which are architecture independent.
"beagleboard" and "qemuarm" are machine specific, "armv5te" and "i586" 
are architecture specific.

These are architecture independent things like scripts/graphics/fonts.

These are machine specific things (you must have built for three
different machines).

> armv5te-poky-linux-gnueabi
> i586-poky-linux
>armv7a-vfp-neon-poky-linux-gnueabi 

These are software built for specific architectures and specific
optimisations within those architectures.

>i686-nativesdk-pokysdk-linux  
> i686-pokysdk-linux

These are parts of the SDK/toolchain (targetted at an i686 SDKMACHINE)

> i686-linux                      

These are "native" software designed to run on the system you're
building on.

Hope that helps!
