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.

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.

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/drbg.mod.o
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)
