* config/global.mk
* config/bin.mk
* src/rdd/Makefile
* Moved central RDD related information to local makefiles.
- Deleted support for $(HB_DB_DRVEXT) envvar.
To extend Harbour with RDDs these should be added as
regular addons, and optionally hbrun rebuilt using hbrun.hbp.
[ $(HB_DB_DRVEXT) is still used from hbmk script, I didn't
touch that part. ]
* INSTALL
* Minor.
