I've successfully build a custom Linux distro for the DE10 nano using Yocto. I am using among other things, meta-openembedded, meta-altera and poky. All of these are set to the dunfell branch.
I am now trying to cross compile software for this custom image using the SDK on Ubuntu 22.04 LTS. The same machine I used to build the distro and sdk.
$ bitbake custom-image-full -c populate_sdk
I've sourced the script

$ cd /opt/custom/1.0/sysroots/armv7at2hf-neon-prose-linux-gnueabi/usr/src/kernel

If I check the glibc version of my Ubuntu 22.04 LTS machine.
$ ldd --version

This is higher than that required by the library inside the sdk.
As far as I understand, it isn't possible or wise to try downgrade my GLIBC version, as its integral to the kernel version. I could perhaps upgrade my recipes to use a newer version than dunfell, perhaps kirkstone, but this is a huge amount of work.
I don't have the option of rolling back my machine to an earlier version of Ubuntu either.
Thanks for the suggestions @Employed Russian and @Yoda. Both your comments lead me toward a solution that worked.
The issue was that my shell environment was polluted. Running unset LD_LIBRARY_PATH didn't work for me, hwoever it made me realize that something in my environment might be causing the wrong library linkage to occur.
To test this idea, I cleared the shell environment:
$ env -i bash --noprofile --norc
Ran the sdk environment script
$ . /opt/custom/1.0/environment-setup-armv7at2hf-neon-custom-linux-gnueabi
Built scripts
$ cd /opt/custom/1.0/sysroots/armv7at2hf-neon-prose-linux-gnueabi/usr/src/kernel
$ make scripts
It builds correctly now.
