Introduced in 565f495544b24df02403d29f5519a1ed73a9952f and the code has never been run?

The syntax error is in testsuite/python_support/utils.py at line 477, in the f-string calling m.dirs.build_dir("src"). Start by inspecting that expression and run the reported testsuite command for testsuite/tests/lkt/import/invalid/. Done means the test compiles past the SyntaxError and the invalid-import test produces its expected result.
