Comment (by phoudoin):
Seems that our putenv() implementation is not POSIX compliant :
http://www.opengroup.org/onlinepubs/009695399/functions/putenv.html
"the string pointed to by string shall become part of the environment, so
altering the string shall change the environment. "
We don't support that, as we always copy the string in
src/system/libroot/posix/stdlib/env.cpp:update_variable().
