Rather than doing this, the base should just be split for an ELF interpreter like PaX. It makes sense for a standalone executable to be as low in the address space as possible. Doing that ASAP fixes issues like this and opens up the possibility of fixing stack mapping ASLR entropy on various architectures. It should be a pretty small change.
