>Description:
I tried to reproduce the official amd64 8.0 build locally.
This worked quite well, but one file has different debug
information:
--- local/usr/libdata/debug/usr/X11R7/lib/modules/drivers/vmware_drv.so.13.debug
+++ releng/usr/libdata/debug/usr/X11R7/lib/modules/drivers/vmware_drv.so.13.debug

This kinda sounds like a binutils bug to me.
>How-To-Repeat:
Checkout netbsd-8-0-RELEASE, try to build an amd64 release
with MKREPRO=yes and compare results to the official
binaries.
The actual command I used was:
/work/src-8/build.sh -m amd64 -B 201807172014Z -D /work/hosts-80r -T /work/tools-80r -R /work/rel-80r -M /work/obj-80r -U -X /work/xsrc-8 -P -x -N0 -V TMPDIR=/var/shm/btmp -V MAKECONF=/tmp/make.conf -V MKDEBUG=yes -j12 release iso-image install-image
(and MAKECONF was an empty file)
