Hmm, don't know if they keep a full log, but the error is

   mm/slub.o: In function `__slab_free.isra.13':
>> (.text+0x1038): undefined reference to `_GLOBAL_OFFSET_TABLE_'  
   scripts/link-vmlinux.sh: line 93: 48917 Segmentation fault  ${LD} 
${LDFLAGS} ${LDFLAGS_vmlinux} -o ${2} -T ${lds} ${objects}

I suspect the change to thin archives, allowed the linker more
flexibility to satisfy all relocations with GOT relative. And
that would cause the bug.

If you could verify that the upstream kernel build succeeds with
an upstream binutils using allnoconfig, then we could see about
updating the kbuild test robot's toolchain.

Thanks,
Nick

OK. I'll ignore this error for now. Sorry for the noise!

FYI, I still suspect it is this bug

https://sourceware.org/bugzilla/show_bug.cgi?id=21017

If so, then I'm not sure if it can be worked around in Linux.

Thanks,

OK, let me try upgrade the debian package first.
What's your toolchain version?


The one that was installed by make.cross from the reproduction

Ah yes. It's a problem with the gcc 6.2 I built recently:

The problem must be at your end, especially if the toolchain exhibits 
segmentation faults.

Following exactly the instructions above, I get:
