I'm not sure if we want to try to modify EPICS base to do this, or if we should just add strip -x to the do_install rule and call it a day.

In the past, I had thought about adding split debug info support to EPICS base so that you can have separate .dbg files with completely stripped binaries. in that case, I think we'd just add those files to a -dbg package or something.

I think we can add strip -x for now and call it a day.
