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.

The redirection of built-in functions such as sqrt in include/math.h
applies when the wrappers for those functions in libnldbl_nonshared.a
are built, resulting in references to internal names such as
__ieee754_sqrt that aren't actually exported from the shared libm.
(This applies for sqrt in 2.28, also for the round-to-integer
functions in current master because of my changes there.) This patch
arranges for NO_MATH_REDIRECT to be used for all the affected
functions, and adds a test for those functions in
libnldbl_nonshared.a.
(We could of course choose to obsolete libnldbl_nonshared.a and
require that people building with -mlong-double-64 either include the
relevant headers and have a compiler supporting asm redirection, or
have some other means of achieving that redirection at compile time if
not including those headers. But while we have libnldbl_nonshared.a,
it seems appropriate to fix such bugs in it.)
Tested for powerpc, and with build-many-glibcs.py.
[BZ #23735]
* sysdeps/ieee754/ldbl-opt/nldbl-compat.h (NO_MATH_REDIRECT):
Define.
* sysdeps/ieee754/ldbl-opt/test-nldbl-redirect.c: New file.
* sysdeps/ieee754/ldbl-opt/Makefile [$(subdir) = math] (tests):
Add test-nldbl-redirect.
[$(subdir) = math] (CFLAGS-test-nldbl-redirect.c): New variable.
[$(subdir) = math] ($(objpfx)test-nldbl-redirect): Depend on
$(objpfx)libnldbl_nonshared.a.
