The patch looks good to me too.  I did see some generated file
differences, most of which disappeared when I compiled my own
autoconf-2.69 rather than using the Ubuntu 18.04 version (which
apparently has some patches from autoconf-2.70 applied).

I applied both of your posted patches, ran autoconf in zlib since
you'd said the posted patch was broken, touched all the files in the
first patch, then built binutils-gdb with --enable-maintainer-mode.
Apart from .pot files, these were the files that differed:

bfd/doc/Makefile.in
binutils/doc/Makefile.in
gas/doc/Makefile.in
gdb/aclocal.m4
gdb/config.in
gdb/configure
gdb/gnulib/aclocal.m4
gdb/gnulib/configure
libdecnumber/aclocal.m4
zlib/configure
