build: show cc outputs when version detection failed

[legendecas]

There are chances that ./configure fails on GitHub Actions.
Print the output of the command to see if there is any way to
improve it.

Example: https://github.com/nodejs/node/actions/runs/21730375777/job/62683227640?pr=61699

make: Entering directory '/home/runner/work/node/node/node'
python3 ./configure --verbose --error-on-warn --v8-enable-temporal-support
sccache: error: Timed out waiting for server startup. Maybe the remote service is unreachable?

I think the failure is due to the sccache error in that output?
