Jdupes 1200
<!-- Mark items with [x] where applicable -->

Despite the flag ENABLE_BTRFS is enabled for make, this seems to be mishandled by the way the Makefile builds the CFLAGS, so the functionality does not get included.

(It does not depend on any BTRFS headers, libraries, or ioctls, only if the appropriate flag is given on run)
