[OE-core] [PATCH 0/3] Initial configuration for the CSL 2011.03 external toolchain for ARM

[Ken Werner]

Hi there,
 
I've spent some time on getting OE-Core compiled with the CSL 2011.03 external 
binary toolchain for ARM GNUEABI. I've started with the existent csl recipe 
and the steps that Tom documented [*] which have been very useful. It turned 
out that only one change to OE-Core was needed to get the minimal image 
working. The pre-configuration step of the libc-package needs to be override-
able by other recipes - just like Tom described. Here is what I've added to my 
local.conf for building the core-image-minimal:
  TCMODE = "external-csl-arm-2011.03"
  ENABLE_BINARY_LOCALE_GENERATION = "0"

In order to build the sato and Qt4-demo images I need a small change to the 
cmake.bbclass that allows cmake to find the binaries of the external toolchain. 
In addition I had to disable localization support to prevent the system to pull
in a dependency to eglibc-locale:
  PACKAGE_NO_LOCALE = "1"
  PACKAGE_NO_GCONV = "1"
  IMAGE_LINGUAS = ""
  LIMIT_BUILT_LOCALES = "POSIX"

Please note that currently the libc is provided by the sysroot of the external 
toolchain. This might not be ideal and as time permits I'd like to find a way 
to get eglibc build instead.

I'm still learning about OpenEmbedded and appreciate any suggestions.

Ken Werner (3):
  Rename do_configure_prepend to do_pre_configure and add it before
    do_configure
  Add EXTERNAL_TOOLCHAIN to CMAKE_FIND_ROOT_PATH
  Add the Sourcery G++ Lite 2011.03 external toolchain for ARM
