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)
