Sounds good. Please do this. I've done something similar trying to get 
the location of the build-tree's message catalogs usable for 
22_locale/messages_*.cc test files.

I'll just merge into your changes.

I don't know how to do this. If you can figure it out, then do it, but 
don't stress too hard about it. If you can't figure if out, just comment 
it in acconfig.h.
