Failed to link libclangTesting.so.21.0git: undefined symbol: llvm::Triple::Triple

Hi!

I'm bumping by local clone of the repo since ~700 commits ago, and now when trying to ninja check-clang-tools, I get:

ld.lld: error: undefined symbol: llvm::Triple::Triple(llvm::Twine const&)
>>> referenced by CommandLineArgs.cpp
>>>               tools/clang/lib/Testing/CMakeFiles/clangTesting.dir/CommandLineArgs.cpp.o:(clang::getAnyTargetForTesting[abi:cxx11]())

I've tried a clean build and get the same result. Is this issue known?

Platform: Ubuntu 20.04, compiling with clang 20
