How do you globally set environment variables for remote execution through ssh?

I am trying to exec a script remotely through ssh from x86 Solaris 8 OpenSSH 4.4 to SPARC Solaris 10 Sun_SSH 1.1.  I can set an environment variable in $HOME/.ssh/environment but need to have this set globally for every user.  I know that ssh does not run any of the usual login files for a remotely executed program but the has to be some file where global item may be set.  Apparently Sun_SSH does not look at the system ssh config files either, like /etc/ssh/environment.
