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.

Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes the remaining double powerpc functions use
libm_alias_double to define function aliases (with consequent removal
of the need for local compat symbol handling). Previous cleanups
avoid this patch changing installed stripped shared libraries for any
build-many-glibcs.py configuration (there are still some functions in
this patch for which the order of double and float aliases changes
within an individual source file, but in this case this doesn't result
in changes to the final library).
Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged for all its hard-float powerpc configurations.

Some powerpc logb implementations define a compat symbol for logbl
based on logb, whereas libm_alias_double defines such a compat symbol
based on __logb instead. This difference (logb is weak, __logb isn't)
is enough to result in different installed stripped shared libraries.
The difference in the installed libraries isn't significant, but first
changing the compat_symbol calls helps make it possible to validate a
subsequent change to use libm_alias_double by comparison of libraries,
so this patch does such a preliminary change.
Tested with build-many-glibcs.py for all its hard-float powerpc
configurations.
