I guess you have some tricky kernel security patches applied?
Normally every libs (starting with ld-linux.so.2 and glibc)
are loaded from 0x40000000.

It was an old issue with l3codeca.acm, which also loaded at
low addresses, and so conflicted with some security patches
which forced libs to be loaded at 0x00xxxxxx addresses.

I wonder if you patch solves the problem correctly, as
afaik loader's relocation code is broken to hell, and
some PE formats arent even implemented there.
