Enable large-file support on systems that do not enable it by default
Invoke AC_SYS_LARGEFILE to enable large-file support.
This fix doesn't change the library as much as the tools because
the only affected function in libattr is attr_copy_action that calls
attr_parse_attr_conf that in turn calls fopen(ATTR_CONF, "r").
What is the most affected is getfattr, without the fix it just cannot
process large files, e.g.
$ truncate -s2G large-file && getfattr large-file
getfattr: large-file: Value too large for defined data type
