Automated rollback of commit 48881f1f453c963e49044210bb1d09b354c83f67. *** Reason for rollback *** Broke a test *** Original change description *** The auto-configured toolchains provided by Bazel itself have diverged heavily from the version maintained in this repo. There is no need to maintain this duplication until Starlarkification has progressed succiciently for rules_cc to be the source of truth for them. This is particularly relevant for Bzlmod, which currently uses the toolchains defined in rules_cc. As a result, Bazel C++ builds will use subtly different toolchains depending on whether --enable_bzlmod is used or not. This is fixed... *** PiperOrigin-RevId: 501228335 Change-Id: I858dc3ea44df7ae70b5603f6dc2e082b4540c42a
