There is [1] from 2021 also with -march, but it was worked around back then and that was several years ago. But could it be the same thing? [1] https://forums.gentoo.org/viewtopic-t-1129458-start-0.html It'd at least explain why the message is showing up... but while the in-tree glibc-2.38 ebuilds do not have the line added in [2], the commit to glibc-9999.ebuild says this is supposed to have been addressed upstream [3].
