I traced through the source to see how SCHILY.fflags can ever
be added to the archive.  I think it depends on whether the
HAVE_STRUCT_STAT_ST_FLAGS test is true when libarchive is built:

 https://github.com/libarchive/libarchive/blob/v3.0.3/libarchive/archive_read_disk_entry_from_file.c#L174

Try the patch below when building CMake against Ubuntu's libarchive.
