Either readelf or objdump for now, and if that proves to be fragile we
can look at a C program. You could do:
readelf -l $vmlinux | grep -m 1 LOAD | awk '{print $4}'
or
objdump -p $vmlinux | grep -m 1 LOAD | awk '{print $7}'
There's not a lot of difference. Since the wrapper already uses
objdump, I think we should use objdump rather than making the wrapper
depend on an additional program (readelf).

I think we would take the first one.
