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

Following exactly the instructions above, I get:

[...]
  LD      vmlinux
  SORTEX  vmlinux
  SYSMAP  System.map
  OBJCOPY arch/microblaze/boot/linux.bin
  Building modules, stage 2.
  MODPOST 3 modules

  CC      crypto/echainiv.mod.o
  CC      crypto/jitterentropy_rng.mod.o
  LD [M]  crypto/jitterentropy_rng.ko
  LD [M]  crypto/drbg.ko
  LD [M]  crypto/echainiv.ko
Kernel: arch/microblaze/boot/linux.bin is ready  (#1)
