building and using modules on arm64 hikey board

I got myself an arm64 HiKey board from LeMaker and build an Android AOSP
image for it (see [1]). For development I would like to use
CONFIG_MODULES. However, when I try to insmod the build module I get:

[ 287.903653] module cfg80211: overflow in relocation type 261 val
ffffffbffc006530

Looking AArch64 ELF documentation [2], section 4.6.5, it has:
code|name |operation |overflow check |
261 |R_AARCH64_PREL32|S + A - P |-2^31 <= X < 2^32|

So basically the highest 32 bits should all be one and so ffffffbf is
invalid. From what I could find searching internet it could be an issue
with linker options so I build kernel and modules with V=1. Here the
linker invocation for them:

+ aarch64-linux-android-ld -EL -p --no-undefined -X --build-id -o vmlinux \
-T ./arch/arm64/kernel/vmlinux.lds arch/arm64/kernel/head.o
init/built-in.o \
--start-group usr/built-in.o arch/arm64/kernel/built-in.o

--end-group .tmp_kallsyms2.o

aarch64-linux-android-ld -EL -r -T ./scripts/module-common.lds
--build-id \
-o net/wireless/cfg80211.ko net/wireless/cfg80211.o
net/wireless/cfg80211.mod.o

Attached are vmlinux.lds and module-common.lds. I also tried taking
upstream arch/arm64/kernel/module.lds in hikey-linaro tree. If someone
can give a hint or educated guess at what to try it would be appreciated.

Arend
