LFS-test

[Andreas Jaeger <aj at suse dot de>]

Below is a fairly basic test for LFS which tests lseek64, stat64 and
open64.

The result on a 2.2.x kernel is:
/home/aj/build-glibc/20000614/io/test-lfs: LFS seems not to be supported.: Invalid argument
- but it exits with 0.

Ok to commit?

2000-06-30  Andreas Jaeger  <aj@suse.de>

	* io/Makefile (CFLAGS-test-lfs.c): New.
	(tests): Add test-lfs.

	* io/test-lfs.c: New file.
