Trying macos-12 in buildRelease.yml since the workflow fails for macos-latest (= macos-14).

Files gcfinal.c and testool.c both contain literal TAB characters embedded

The output formatting depends on the user's simulated tab settings and
therefore may not produce the expected results.

The output formatting is rewritten to make tab characters unnecessary.
