This breaks the use of simple "make", as it just makes btrfs-list.o
and nothing else. This new target should probably be put somewhere near the bottom of the file, not above the "all" target, where it becomes the default:

hrm@ruthven:btrfs-progs-unstable $ make
bash version.sh
ls btrfs-list.c

Re: [PATCH 1/3] add all targets to clean target

Quoted 14 lines · Andreas Philipp

When issuing 'make clean' not all files generated by the individual targets have been deleted since some files have been missing in the definition of the 'make clean' target.
