nose2 recognizes this as a test:
$ support/testing/run-tests --list 2>&1 | grep Toolchain | head -n1
test_run (tests.toolchain.test_external.TestExternalToolchain) ... ok

and it tries to run it when --all is used:

ERROR: test_run (tests.toolchain.test_external.TestExternalToolchain)

I think you could avoid this by renaming this method ...

https://nose2.readthedocs.io/en/latest/usage.html#naming-tests
'Within test modules, nose2 will load tests from unittest.TestCase subclasses,
and from test functions (functions whose names begin with "test").'

... to something like this:
    def common_check(self):
...

... and changing all calls to something like this:
        self.common_check()
