With KBUILD_VERBOSE=1 I see:
...
/bin/bash /home/benh/linux-4.8.15/arch/powerpc/boot/wrapper -c -o
arch/powerpc/boot/zImage.pseries -p pseries vmlinux
ld: arch/powerpc/boot/zImage.pseries: Not enough room for program headers,
try linking with -N
ld: final link failed: Bad value
and then with tracing enabled for that shell script:
...
+ ld -m elf64lppc -T arch/powerpc/boot/zImage.lds -pie -o
arch/powerpc/boot/zImage.pseries arch/powerpc/boot/pseries-head.o
arch/powerpc/boot/of.o arch/powerpc/boot/epapr.o ./zImage.15656.o
arch/powerpc/boot/wrapper.a
ld: arch/powerpc/boot/zImage.pseries: Not enough room for program headers,
try linking with -N
ld: final link failed: Bad value
Let's try without that -pie:
$ ld -m elf64lppc -T arch/powerpc/boot/zImage.lds -o
arch/powerpc/boot/zImage.pseries arch/powerpc/boot/pseries-head.o
arch/powerpc/boot/of.o arch/powerpc/boot/epapr.o ./zImage.15656.o
arch/powerpc/boot/wrapper.a
$
Surprise, it works! So we need to filter out -pie here as well. (Or
disable building these wrappers, since we don't actually package them.
But that doesn't seem to be a kconfig option)

Q. Which is the greater problem in the world today, ignorance or
apathy?
A. I don't know and I couldn't care less.
