He current guidance is on the wiki:

<https://sourceware.org/glibc/wiki/Contribution%20checklist#Update_copyright_information>

It currently suggests

for the FSF case (no Signed-off-by: in the commit message), and

     Copyright The GNU Toolchain Authors.

for Developer Certificate of Origin case.
