This is a speculative fix for TestRosetta.py which is currently failing on Green Dragon.

TestRosetta just makes sure we can debug an x86_64 process on Apple Silicon. However, we're failing to build the x86_64 test binary. The linker is failing with some warnings about libc++ and libunwind being build for arm64 while the target binary is x86_64. I'm going to try building with the system standard libraries instead of the just-built ones to workaround it.
