FYI, I've been working on a way to automate this for some time, and now
think I have a recipe which works.  This allows a built directory tree
to later be moved and used from a different location.

Also, it also adds epicsGetExecDir() which, by way of a zoo of OS specific
mechanisms, gives the directory containing the executable which started the
current process.  This enables eg. the softIoc executable to find softIoc.dbd
regardless of $PWD and without a compiled in $(FINAL_LOCATION).
