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

Following exactly the instructions above, I get:

[...]

  SORTEX  vmlinux
  SYSMAP  System.map
  OBJCOPY arch/microblaze/boot/linux.bin
  Building modules, stage 2.

CC Michal. It looks like a microblaze specific error. I'll blacklist
this old error on microblaze if there are no good solutions.

Sorry for the noise!

It doesn't exhibit any build error on my end.  Which is why I suggested 
that you verify the integrity of your toolchain on your end.

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 
instructions included in the error report below. Currently:

gcc version 4.9.0
GNU ld (GNU Binutils) 2.24

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

The below 2 both works. I'll revert to the working gcc 4.9.
