clang-9: error: linker command failed with exit code 1 (use -v to see invocation)
While the LLVM support libs above are all 32-bit only, xray only supports
x86_64, but doesn't detect the mismatch, thus the failing links.
I've hacked around this in lib/xray/tests/CMakeLists.txt (add_xray_unittest)
but am unclear about the proper condition to use.
