What worries me here is that we are beginning to add a enviroment variable
for each and every command line option of qemu linux-user. I think it would
be better to have a wrapper binary to be registered as the binfmt runner.
Alternatively we should have a generic setup for mapping enviroment variables
to command line options. Now we get special per-option code every time someone 
needs to setup a command line option from binfmt.
