I don't count this as a bug. The ELF spec allows shared objects to be
loaded with any load address. In fact it's great we are non-standard here
-- this makes catching bugs easier. I've already found and fixed a few
bugs in gdb thanks to this difference.

I insist there is a kernel bug only. We might change the enforced base
address within ld.so one day to be more like other archs, but let's keep
it for now -- this really benefits.
