Description of the bug:

Bazel 7.0.0 fails to build the stage1 portion of the bazelbuild/examples/cpp-tutorial. It appears to fail to resolve a path it constructs.

Reverting to Bazel 6.4.0, or passing the --noincompatible_sandbox_hermetic_tmp build option, are both successful workarounds.

2. Clone https://github.com/bazelbuild/examples, and change into the examples/cpp-tutorial/stage1 directory.
3. Execute bazelisk-linux-amd64 build //main:hello-world.
4. As part of the build failure output, receive the following error message:

external/gcc_toolchain_x86_64/bin/gcc: line 45: /tmp/external/gcc_toolchain_x86_64_files/bin/x86_64-linux-gcc: No such file or directory
