Commit d5ea873f is not the same as the the following original Eric's patch.

http://oss.sgi.com/archives/xfs/2010-06/msg00080.html

It does not modify src/Makefile and realpath is never compiled.

In addition, `[ -L $TEST_DEV ]' and `[ -L $SCRATCH_DEV ]' always returns 0
if $TEST_DEV or $SCRATCH_DEV are not defined.
