It would be better to just fix all calls in qemu than
to add a new personality. There aren't that many anyways.
personality is really more a kludge for bug-to-bug compatibility
with old binaries (that is where the 3GB personality came from
to work around bugs in some old JVMs that could not deal with a full 4GB
address space), it shouldn't be really used for anything new.
