I used these shell commands:
../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")
and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 7061 files FOO.
I then removed trailing white space from math/tgmath.h,
support/tst-support-open-dev-null-range.c, and
sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following
obscure pre-commit check failure diagnostics from Savannah. I don't
know why I run into these diagnostics whereas others evidently do not.

Optimize memrchr with AVX2 to search 32 bytes with a single vector
compare instruction. It is as fast as SSE2 memrchr for small data
sizes and up to 1X faster for large data sizes on Haswell. Select
AVX2 memrchr on AVX2 machines where vzeroupper is preferred and AVX
unaligned load is fast.
* sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add
memrchr-sse2 and memrchr-avx2.
* sysdeps/x86_64/multiarch/ifunc-impl-list.c
(__libc_ifunc_impl_list): Add tests for __memrchr_avx2 and
__memrchr_sse2.
* sysdeps/x86_64/multiarch/memrchr-avx2.S: New file.
* sysdeps/x86_64/multiarch/memrchr-sse2.S: Likewise.
* sysdeps/x86_64/multiarch/memrchr.c: Likewise.
