[patch] Properly detecting large file support

[Neal H Walfield]

This patch properly detects large file support.  Before, GNU/Parted only
checked to see if large file support was on.  This now looks to see if
large file support is available.

This has been test on both GNU/Hurd and GNU/Linux.

        * configure.in: Correctly detect large file support using
        AC_SYS_LARGEFILE, not getconf LFS_CFLAGS.
