I have never used the Altera tools because they are are difficult to work
with compared to normal Linux tools.
Have you ever tried using buildroot as a build environment? That works

That said, building a squashfs file system is very simple it is just a step
in the final rootfs packaging. It should be quite easy to use that instead.
