[PATCH] - Introduce reference to a new Emacs build target - NaCl

[Pete Williamson]

I would like to request feedback on this patch for the emacs configure.ac file.

As I mentioned in previous patch requests, I'm adding support for a new build target, the chromium browser's Native Client (NaCl) platform.  We have a patch for emacs working today (for some definitions of working ^_^) in NaCl ports, and we would like to port the changes back to the emacs code base.

Is this the right way to introduce a new build target?  Once this is checked in, I have more changes for the config.ac file, but I wanted to vette the approach with the good folks on this email list before proceeding.

For a preview of the other changes I hope to port to the configure.ac file, here is a list of changes in our port today, I hope to port most or all of these to the regular emacs code base in future patches.
