Set PYTHON_TARGETS=pytthon3_6. This will ensure portage and its dependencies are built for python3.6. You can then set python3.6 as the default interpreter globally by putting it first in /etc/python-exec/python-exec.conf. There's a comment with instructions at the top of that file. If you only want emerge to use python3.6, put it in /etc/python-exec/emerge.conf instead.
