'python' here for me is Python 3.11. Now, if I do EPYTHON=python3.10 aarch64_be-unknown-linux-gnu-emerge -v1 dev-lang/python:3.10, it works! So, we need a CBUILD Python which is the same version, apparently. Or at least not newer, but I'm guessing we actually do need the same version? (Note that we've already implemented this logic for Python 3.11.)
See also: https://github.com/openembedded/openembedded-core/blob/master/meta/recipes-devtools/python/python3/crosspythonpath.patch https://cgit.openembedded.org/openembedded-core/tree/meta/recipes-devtools/python/python3/python3-use-CROSSPYTHONPATH-for-PYTHON_FOR_BUILD.patch?h=pyro https://cgit.openembedded.org/openembedded-core/tree/meta/recipes-devtools/python/python3/000-cross-compile.patch?h=pyro But yeah, we get the problem. We just need to do the Python 3.11-style build-a-Python-for-CBUILD, I think, possibly with a minor build system tweak, but PATH may be enough.
We can set PYTHON_FOR_BUILD.

This avoids an issue where setup.py can't handle deducing libdir (or even being passed it) for cross-compilation. Fortunately, cpython is migrating away from setup.py to autotools. Note that this isn't the same as what bug 633712 would've been at the time it was reported, but it certainly showed up the same way on more modern Pythons since we introduced the CBUILD part a few months ago.
