Tests fail or are ignored when building Swift version 5.9-dev for aarch64 Linux

I'm getting some failing tests:

Failed Tests (1):
  swift-package-tests :: test-sourcekit-lsp/test-sourcekit-lsp.py

Testing Time: 83.15s
  Unsupported: 10
  Passed     : 20
  Failed     :  1
ERROR: command terminated with a non-zero exit status 1, aborting
ERROR: command terminated with a non-zero exit status 1, aborting

It seems to be unhappy with Python?

My Python is 3.9.2.

Also I did specify no_test when I started the build, so I don't know why it's testing.

swift/utils/build-script -j3 --preset=buildbot_linux,no_test install_destdir=~/swift-install installable_package=~/swift.tgz

The no_test presets still run the integration tests on the final toolchain, looks like one is failing for you.
