Fedora 31 crosscompilation fdt problem mimics debian 888789

[kf5zmi]

This dont look right to me.    "aarch64-linux-gnu-2.30-6.fc29.x86_64"

One's I've built have GCC TGT's that look like this in arm64    aarch64-lfs-linux-gnu   or  aarch64-unknown-linux-gnu

[ This was being compiled inside of a qubes-4 fedora-29 instance. eg 'sudo dnf install -y binutils-aarch64-linux-gnu ' to setup. What I want is a way to cross-build an ayefun at least for a client. I need this to improve the security. But my own security has been problematical.]

So one hurdle is  setting     --host  --build   --target  correctly.     Have a look at the old clfs.org web site books for ideas. 

If you want to give some more  info on what docs or guide you're using I may be able to help in a general way.
I am building Linux From Scratch systemd v9 on the board not on x86 at the moment.    Host=Armbian bionic for rock64. 
Really quite fascinating and not for noobs.

I looked far / wide for some docs to do it on x86.64 but no luck.    Some valiant attempts was all I found.

I'd still like to find the right guide.

[Thx for your help]
