Hi,

It seems this patch introduces a compile error on powerpc 85xx platform with
CONFIG_RELOCATABLE enabled.

To reproduce the problem, I compiled the mainline linux kernel with patch
99cb0d917ffa ("arch: fix broken BuildID for arm64 and riscv"), using 
configure
file:

arch/powerpc/configs/85xx-32bit.config

and enabled CONFIG_RELOCATABLE manually. Then the compile log with
Segmentation fault appeared as below:

   ...
   AR      fs/proc/built-in.a
   AR      fs/built-in.a
   AR      built-in.a
   AR      vmlinux.a
   LD      vmlinux.o
   OBJCOPY modules.builtin.modinfo
   GEN     modules.builtin
   MODPOST vmlinux.symvers
   UPD     include/generated/utsversion.h
   CC      init/version-timestamp.o
   LD      .tmp_vmlinux.kallsyms1
Segmentation fault (core dumped)
scripts/Makefile.vmlinux:34: recipe for target 'vmlinux' failed
make[1]: *** [vmlinux] Error 139
Makefile:1252: recipe for target 'vmlinux' failed
make: *** [vmlinux] Error 2

Could anyone reproduce above error, or have I missed anything else?

Thanks,
Jiahao
