In #28519 /791ce593ceI made linux headers be intended to be used from the stage stage, as it would be if it were a library containing headers and code. I forgot to update glibc, however, so it was incorrectly using headers for the build platform, not host platform. This fixes that, basically reverting a small portion of changes I made a few months ago in25edc476fdand its parent. No native hashes are changed.
