Well, you need to update the documentation in install.texi of what the 
arguments to test-wrapper-env look like.  But I'm not aware of any wrapper 
implementations that don't just go through env (whether by using 
cross-test-ssh.sh, or the default empty wrapper), though in principle you 
could have such an implementation (e.g. using userspace QEMU, where the 
program "env" may not exist in a form it can execute ... not that I know 
if userspace QEMU actually has a suitable mechanism for setting 
environment variables that only apply to the emulated program and not to 
QEMU itself).  A NEWS entry mentioning the new requirements might still be 
a good idea.
