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
TOOLCHAIN_SYSPATH = "[email protected]('TARGET_ARCH', d, 1) !=
bb.data.getVar('BUILD_ARCH', d, 1) and
os.path.abspath(os.path.dirname(bb.which(bb.data.getVar('PATH', d, 1),
bb.data.getVar('TARGET_PREFIX', d,
1)+'cpp'))+'/../'+bb.data.getVar('TARGET_SYS', d, 1)) or ''}"
TOOLCHAIN_PATH = "$...@bool(bb.data.getVar('TOOLCHAIN_SYSPATH', d, 1)) and

bb.fatal('No valid toolchain in PATH')) or ''}"
SDK_PATH = "$...@[bb.data.getvar('TOOLCHAIN_PATH', d, 1),
bb.data.getVar('META_SDK_PATH', d,
1)][bool(bb.data.getVar('META_SDK_PATH', d, 1))]}"
# Set the necessary variables to use binary CodeSourcery Lite
TARGET_VENDOR = "-none"
TARGET_CPPFLAGS_append = " -I${SDK_PATH}/${TARGET_SYS}/libc/usr/include "
TARGET_LDFLAGS_prepend = " -L${SDK_PATH}/${TARGET_SYS}/libc/lib
-Wl,-rpath-link,${SDK_PATH}/${TARGET_SYS}/libc/lib "
TOOLCHAIN_TYPE = "external"

Thanks, this looks like something to try.
I'm having a bit of trouble with the setting of 'TOOLCHAIN_SYSPATH'
(my toolchain is home-grown. not CSL). Is there some way to debug this
line, e.g. print out the components and results?
Here's what I'm getting:
$ bitbake minimal-image

How can I debug what 'TOOLCHAIN_SYSPATH' is evaluating to?
Thanks
