don't use cc_wrapper.sh when specify toolchain from local absolute path?

as title, in such a scene, wouldn't meet https://github.com/bazelbuild/bazel/issues/7746??, if dn't use a wrapper script, we can see which compiler used directly

Start by locating cc_wrapper.sh and the code path used when a toolchain is specified by a local absolute path. Read the linked Bazel issue 7746 for the reported behavior, then determine the expected direct compiler selection and how completion should show which compiler was used.
