Could you check if the following directory tree is built after executing the below command?

I actually spotted a build error that was unnoticed last time:
make[2]: Entering directory '/home/jarkko/devel/tpm/optee/edk2/BaseTools/Tests' /bin/sh: 1: python: not found
I'd prefer not to install Python2. It has been EOL over a year.
AFAIK, everything should build fine with Python3. On my Ubuntu 20.04 machine, this is accomplished by installing package "python-is-python3" (after uninstalling "python-is-python2" if need be).
$ ls -l /usr/bin/python lrwxrwxrwx 1 root root 7 Apr 15 2020 /usr/bin/python -> python3
Right, just found about this in unrelated context :-) [*]
Hope this will work out...
Now I get
Traceback (most recent call last): File "/home/jarkko/Projects/tpm/optee/edk2/BaseTools/Tests/RunTests.py", line 36, in <module> allTests = GetAllTestsSuite() File "/home/jarkko/Projects/tpm/optee/edk2/BaseTools/Tests/RunTests.py", line 33, in GetAllTestsSuite return unittest.TestSuite([GetCTestSuite(), GetPythonTestSuite()]) File "/home/jarkko/Projects/tpm/optee/edk2/BaseTools/Tests/RunTests.py", line 25, in GetCTestSuite import CToolsTests File "/home/jarkko/Projects/tpm/optee/edk2/BaseTools/Tests/CToolsTests.py", line 22, in <module> import TianoCompress File "/home/jarkko/Projects/tpm/optee/edk2/BaseTools/Tests/TianoCompress.py", line 69, in <module> TheTestSuite = TestTools.MakeTheTestSuite(locals()) File "/home/jarkko/Projects/tpm/optee/edk2/BaseTools/Tests/TestTools.py", line 43, in MakeTheTestSuite for name, item in localItems.iteritems(): AttributeError: 'dict' object has no attribute 'iteritems'
Right. Same here after removing all traces of Python2 from my system :-/
A couple of fixes are needed:
- EDK2 needs to be upgraded to tag or later [1]
- The PYTHON3_ENABLE environment variable needs to be set to TRUE [2]

BTW, Is to *really* impossible to test this with plain BuildRoot. It's obvious that this forks BR internally.
I mean even if I get this working once, this will feels like a clumsy way to test Aarch64 regularly. I use BuildRoot extensively for x86 testing. And it would be nice to be able to start doing regular ARM testing.
The mainline BuildRoot does have bunch of BR2_PACKAGE_OPTEE_* included. Are they all broken?
Here's a reference where I got with that endeavour:
