This is almost certainly related to AVR32 support, so I think in this
case it was justified to ask here.
It is a user question in so far that "configure --help" has the answer:
  --disable-largefiles   disable support for files > 2GB [enable]
thus largefile support must be explicitly disabled if you do not want
it.
The reason is that systems without it can not even play DVDs properly,
so hardly anyone will want it disabled.
Also it will not usually break builds, systems without largefile support
usually just ignore _FILE_OFFSET_BITS and _LARGEFILE_SOURCE.
