Hi,

I see that you copied most of toolchain setup in your local.conf from arago. 
But, in reality, you don't need all that. I haven't tried external toolchain 
with Agstrom lately, but you should only need to setup these 4 variables:

TOOLCHAIN_PATH = "/opt/arm/arm-2009q3"
TARGET_VENDOR = "-none"
TOOLCHAIN_TYPE = "external"
TOOLCHAIN_BRAND = "csl"

You may also need PATH_prepend like in your example below, if you don't set 
your system PATH accordingly before using OE. Everything else should be taken 
care by the framework automatically.
