But then that doesn't work either, because it only adds
$(BR2_COREUTILS_HOST_DEPENDENCY) in DOWNLOAD_DEPENDENCIES for python
packages that don't specify a _SITE variable.

But the blake2 hash support is completely unrelated to Python: any
other package could use it, not necessarily a Python package. Or could
be a Python package that specifies _SITE explicitly.

Indeed, but see above :-)

(Also, this line adding $(BR2_COREUTILS_HOST_DEPENDENCY) the
dependencies would definitely need a comment)
