- add "-M metalog". if metalog starts with "${DESTDIR}/", it
will be skipped in the flist check, to prevent unnecessary
warnings about extraneous ./METALOG
- if the diff returned a non-zero exit code, print a warning message,
and for the default diff output, print a blurb describing the
meaning of the output.
Makefile:
- call checkflist with "-M ${METALOG}" if UNPRIVED
- run "${MAKE} checkflist" if ${DESTDIR} != ""
NOTE: this change will prevent maketars from running if the
sets lists are out of date. This is intentional.
Better to fail than to build tar files with missing files.
