this is the same issue as fixed by

The problem can be observed with 3d77e6a8804ab ("Linux 5.7").
So it appears that 7883a14339299 ("scripts/kallsyms: fix wrong 
kallsyms_relative_base") is not sufficient to fix it.

Does your problem happen on the latest kernel?

Unfortunately this cross compiler (gcc 4.6.4) is too old to build 
v5.8-rc1 or later. I will have to upgrade.

Which version of binutils are you using?

This toolchain uses binutils 2.22.

In case it helps,
