Absolutely.
In the meantime, I found out that I could re-use an existing variable,
TOOLCHAIN_EXTERNAL_PREFIX which contains exactly what I expected
"gcc -dumpmachine" to return. So I've switched to using that, and it
"fixes" the use-case for internal toolchains as well as a side effect.
I'll resubmit later today...

Meh... :-]
