[Buildroot] [RFC] *clean targets

[Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>]

Hi,

Currently the clean target (as well as dirclean) does nothing useful.

I propose the following change:

# wipe target
clean:
# remove generated files, retain configs
realclean:
# remove generated files, including configs (but not DL_DIR!)
distclean:
# roll a release tarball, in gz, bz2, xz format
release:

hm, something like this as a base (probably incomplete, but better than
what we have now)
