ERROR: RBE was enabled via the 'rbe' env in the 'TFCI' variable.
TFCI: $TFCI
TFCI_BAZEL_TARGET_SELECTING_CONFIG_PREFIX is "$TFCI_BAZEL_TARGET_SELECTING_CONFIG_PREFIX".
But in .bazelrc, there is no "rbe_$TFCI_BAZEL_TARGET_SELECTING_CONFIG_PREFIX".
That setting must exist for this script to function correctly.
