A configure check probably isn't needed.  You can probably just
use sizeof(off_t) at compile time.

If you want to do it at configure time, make sure that you properly
enable LFS support in the configure script.

The proper way to get the CFLAGS for LFS support is:
getconf LFS_CFLAGS

enough and will not work on all arches in Debian.
