Haven't investigated so far, but all 32-bit builds for x86 on Debian unstable
gcc (Debian 10.2.1-6) 10.2.1 20210110
fail for me with
FATAL: modpost: section header offset=11258999068426292 in file
'vmlinux.o' is bigger than filesize=509598908

(hex value is 28000000000034)

Replacing
#if KERNEL_ELFCLASS == ELFCLASS32
with
#if 1

in scripts/mod/modpost.h fixes it to me.

As said, I haven't done any work to find the root cause, so JFYI.

P.S. Yes, I did a completely clean build and tried different kernel
configurations including just default i386_defconfig in the release,
the same error. x86_64 builds are good.
