[yocto] external toolchain

[Dallas Clement]

I'm trying to use an external pre-built toolchain to build my distro.
I added a "TCMODE ?= "external-sourcery" to my local.conf and modified
the external-sourcery include file as follows:

diff --git a/meta/conf/distro/include/tcmode-external-sourcery.inc
b/meta/conf/distro/include/tcmode-external-source
index 1635eec..3ba564a 100644

"/opt/armada-sdk-5.0-64k/armv7-marvell-linux-gnueabi-softfp"

 TOOLCHAIN_PATH_ADD = "${EXTERNAL_TOOLCHAIN}/bin:"
 PATH =. "${TOOLCHAIN_PATH_ADD}"

 CSL_TARGET_SYS_powerpc ?= "powerpc-linux-gnu"
 CSL_TARGET_SYS_powerpc64 ?= "powerpc-linux-gnu"
-CSL_TARGET_SYS_arm ?= "arm-none-linux-gnueabi"
+#CSL_TARGET_SYS_arm ?= "arm-none-linux-gnueabi"

 CSL_TARGET_SYS_mips ?= "mips-linux-gnu"
 CSL_TARGET_SYS_mipsel ?= "mips-linux-gnu"
 CSL_TARGET_SYS_mips64 ?= "mips-linux-gnu"

bitbake is able to find my toolchain, but it eventually fails trying
to install the external sourcery toolchain for arm.

Should I be modifying this external-sourcery-toolchain recipe to point
to my toolchain sysroot area?  Just not sure what all needs to be done
to use my own toolchain.

Thanks
