[Acl-devel] [PATCH acl] Enable large-file support on systems that do not enable it by default

[Dmitry V. Levin]

Invoke AC_SYS_LARGEFILE to enable large-file support.

This fixes acl_get_fd and acl_get_file that invoke *stat functions,
as well their users, perm_copy_fd and perm_copy_file.

The tools are the most spectacularly affected because without the fix
they just cannot process large files, e.g.

$ truncate -s2G large-file && getfacl large-file
getfacl: large-file: Value too large for defined data type
