I'm not qualified to answer this.
Having stated my disclaimer, it's an interesting question and so I'm thinking out loud...

The following article mentions inittab: http://www.ibm.com/developerworks/library/l-linuxboot/
but inittab is missing in modern Debian/Ubuntu.  What about /etc/init/rc.conf ?  There
are a couple of export statements in there.  Since init is the first "userspace" program and
the parent to all subsequent processes it seems like a good location to start.

Ah, now Rich mentions /etc/env.d - but I don't have that in my Linux Mint 13 system.
There is /etc/init/rc.conf with a couple of "export" statements.

HTH and good luck.
Eric
