Kernel module loading failing for Allwinner kernel build with binutils >2.35

Describe your issue

When compiling a kernel (tested only with linux-postmarketos-allwinner) I am not able to load modules. I get insmod errors with "invalid module format". Tested with both the Pinephone and Pinetab. Downgrading binutils-aarch64 to version 2.34 and recompiling the kernel resolves the issue.

Modules loading successfully
