Re: [PATCH][Ping v6] Environment variables forwarding

The issue of passing environment variables to spawned
programs came up on the GDB list recently, although in our case,
we want to pass env vars to host programs (to GDB), not
target programs.

At https://sourceware.org/ml/gdb-patches/2014-06/msg00246.html,
Yao pointed at an earlier dejagnu attempt to address this issue,
at http://lists.gnu.org/archive/html/dejagnu/2008-07/msg00000.html.

I'd be great to have this finally addressed, though whatever
solution dejagnu ends up with should consider build vs board vs target.
