they're the same, I didn't knew about these function.

By looking closer, the code in libutil is almost the same as found in
4.4Lite. It is however way bigger than the FreeBSD code:

% size libc/gen/strtofflags.o libutil/stat_flags.o
  text    data     bss     dec     hex filename
   706     168       0     874     36a libc/gen/strtofflags.o
  3785       0       0    3785     ec9 libutil/stat_flags.o

maybe could the current code and FreeBSD/DragonFly version be merged.
Then creating an alias flags_to_string(3) <-> fflagstostr(3) to
support both API ?
