You could edit the .ecc file and rerun 'ecosconfig tree'.  Editing the
hal.h file is useless as it may get regenerated.

More importantly, it would be useful to find out why this is being
set the way it is.  You can figure this out by reading the .ecc file.

Probably not much beyond the CDL files themselves.

Of course, if you want to contribute some documentation on the subject,
it would always be welcome :-)
