Maybe I'm missing something somewhere...

Reproducible: Always

Same goes with other external module, e.g. net-misc/r8168.

Sorry, the above reference link content is faulty.

Here's a valid snippet instead:

Comment 3 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2023-01-26 06:52:30 UTC
How are you building your kernel? If doing it manually, it probably calls gcc via 'gcc' and not the full tuple name, while ebuilds prefer it in full as behaviour can vary.

CONFIG_CC_VERSION_TEXT in e.g. /proc/config.gz should tell you. In any case, it's not a problem, just noisy.
