I'd like to see if Chris has an idea. Adding patches for each<br>
architecture/bsp is not preferred. It might be that we can pick up the<br>
target (architecture, bsp) in the build script, and add some code to<br>
parameterize the EPICS configuration. This file-based configuration is<br>
a little bit clunky in EPICS.<br>
