[Buildroot] Error when installing to staging directory

Yes, I am running with fresh clone 2017.11.x. I do not copy, or modify any files in buildroot folder. 
I am using external compiler: 
In my $ROOT I have:
$ ls
bashrc.local  build  build_all.sh  defconfig  overlays  post-image.sh  pre-image.sh  skeleton

and I run: $source build_all.sh

source bashrc.local
if [ ! -d buildroot ]; then
	git clone git://git.busybox.net/buildroot
cd buildroot
git checkout origin/2017.11.x
cd $ROOT
cp defconfig/defconfig build/.config
if [ -f Makefile ]; then
	# first run
	make O=$ROOT/build -C ~/buildroot     #build folder is created manually

export ARCH=arm
export ROOT=$PWD
export CROSS_TOOL_PATH=/tmp/gcc-linaro-7.1.1-2017.05-x86_64_arm-linux-gnueabi      #copied manually to this location
export CROSS_TOOL_PREFIX=arm-linux-gnueabi

I am reading "host/ contains the installation of tools compiled for the host that are needed for the proper execution of Buildroot, including the cross-compilation toolchain." I also compared the contents of host/ now and when it was working and it is different.
I expect to have: arm-buildroot-linux-gnueabi  bin  doc  etc  include  lib  lib64  libexec  man  sbin  share  usr  var
But I currently have: arm-buildroot-linux-gnueabi  bin  lib  lib64  share  usr
Maybe because of the previous error that is not printed to the screen. So there are obvious missing folders. I think these are the part from cross compiler. 
$ ls /tmp/gcc-linaro-7.1.1-2017.05-x86_64_arm-linux-gnueabi/
arm-linux-gnueabi/                           lib/
bin/                                         libexec/
gcc-linaro-7.1.1-2017.05-linux-manifest.txt  share/

Would you mind testing with 2018.11?

When you copy over to the new location, is it a fresh 2017.11 git
clone?  Are you using a target that's already in buildroot or are
there additional files you copy into the buildroot folder after GIT

You mention doing a out of tree build.  I assume that folder is never
relocated and always created new when you do your "make O=<out of tree
location> <defconfig name>_defconfig" to setup your build?

Not necessarly, it's a way you can manage customization but not
required.  Checkout details in the manual about keeping customizations
outside of buildroot if you have interest in that.

Unless it is hidden by .gitignore... What could possibly cause this error? As far as I see, everything in /host directory is populated by the Buildroot process. So why the sysroot/usr is missing? Am I missing to export another environment variable for Buildroot that gets set once when you run it first time and always there unchanged? Please help.
