The difference between armhf and amd64 regarding the fstype binary is:
armhf:
fstype loads at 00010000 and klibc.so loads at 40000000
for amd64:
fstype loads at 00400000 and klibc.so loads at 00200000

So, on amd64 the brk region is above both elf binaries,
while on armhf if clashes with the klibc areas.
