[oe] External toolchain

[Luca Bolognini]

Hi,
I would like to use an external toolchain (CodeSourcery2009q1) to 
cross-compile some packages for my beagleboard (more or less the same 
that happens in Arago) and then I expect not to download glibc package 
and cross-compile again libc, libpthread and so on. I would like to use 
the libraries inside my external CodeSourcery SDK.
I followed some 
hints by Denys and Tom ( http://lists.linuxtogo.
org/pipermail/openembedded-devel/2010-April/019521.html ) and I put 

# 
LUCA
TARGET_VENDOR = "-none"
TOOLCHAIN_TYPE ?= "external"

TOOLCHAIN_BRAND ?= "csl"
TOOLCHAIN_PATH = "/opt/ti/codesourcery"

TOOLCHAIN_SYSPATH = "${TOOLCHAIN_PATH}/arm-none-linux-gnueabi"

PATH_prepend = "${TOOLCHAIN_PATH}/bin:"
require 
conf/distro/include/toolchain-external.inc

inside my 
openembedded/conf/distro/angstrom-2008.1.conf

As you know, cross-
compiler provided by CodeSoucery is arm-none-linux-gnueabi-gcc but I 
get the following error with libtool-cross_2.2.6b.bb:

Obviously OE doesn't have to find arm-angstrom-linux-
gnueabi-gcc, but why does it search for arm-angstrom-linux-gnueabi-gcc 
instead of arm-none-linux-gnueabi-gcc ?
What's wrong inside angstrom-
2008.1.conf or what am I missing?

Thank you for your support
Luca
