I'd like to use my own toolchains when building OpenEmbedded.
I've tried to follow the information at:

It's a bit terse and confusing, so I'm just trying to see
what I need (I think the section tries to discuss too many
concepts at once)
If you're using angstrom and want to use a prebuilt CSL toolchain, you
only need to add this to local.conf (I suspect thunderbird will linewrap
it):
# Black magic to automatically set SDK_PATH out of PATH - don't touch this!
# Works with pretty much any external toolchain, like CS Lite or MV Pro 5
# Handles cross-toolchain vs. native toolchain
# SDK_PATH can be overwritten externally by META_SDK_PATH, e.g. for SDK

TARGET_VENDOR = "-none"

Sadly, this is not working. I installed the latest CSL toolchain
for my platform (to be pedantic; I really want to use my extant tools).
Anyway, I now get this error:

Any ideas?
