In the previous update commit, the Nix `cc.version` didn't match the in-output directory name anymore, causing a build failure. By asking GCC properly, we are robust against such discrepancies. The script isn't great, relying on GCC "log" output specifics, but it seems that the GCC output has been like this for a while, and the lines before and after seem to be intentional about their purpose... (cherry picked from commit 68f928555660cb914105b0ad668d6cadc25223e9)
