Okay, yep, that wasn't it at all.

It simply parses /var/local/system/locale & /var/local/system/tzVar to add LANG, LC_ALL & KINDLE_TZ to the env.

Simple testcase with env & environ:

[root@kindle root]# env -i ./environ 
LANG=en_US.utf8
LC_ALL=en_US.utf8
KINDLE_TZ=GMT+01:38

EDIT: I guess I could have gone with Python, too. meh.

environ.c

#include <unistd.h>
#include <stdio.h>

extern char **environ;

main()
{
        int i = 0;
        while(environ[i]) {
                printf("%s\n", environ[i++]);
        }
}

env.py

#!/usr/bin/env python2

import os

for key in os.environ.keys():
    print "%s=%s" % (key,os.environ[key])
