I've not merged this as yet since I worry that this is something we'd
easily break again. It all depends which order classes are included and
moving the cross-canadian inherit in meta-environment would break this
even with immediate expansion.
I think the best way to fix this might be to change the meta-
environment to add:
# Need to expand here before cross-candian changes HOST_ARCH -> SDK_ARCH
TOOLCHAIN_CONFIGSITE_NOCACHE := "${TOOLCHAIN_CONFIGSITE_NOCACHE}"
before it inherits cross-candian, then the problem is explicitly
recorded and worked around.
Cheers,
Richard
