I heard a similar report from Olof when his autobuilder produced 100%
failure.  I tried one of the same defconfig's that Olof tried here,
and didn't see the failure.  It passes my build tests here, and it
also passes kernelci's build tests too.

So, I _think_ it's got something to do with the toolchain versions
being used, but at the moment I'm just guessing.  I've no real idea,
because I've no idea what's causing the failure at the moment.

Olof said that he'd send me one of the build trees, but I'm still
waiting.

What I need is a tarball of the objects from arch/arm/boot/compressed
to work out what's going on - when grabbing that, it may be a good
idea to first disable the assert in the linker script, so that the
resulting "vmlinux" in that directory remains for analysis.  Or...
someone else needs to work out what's going on and report back.
