Details:

When the test setup phase of 
find/testsuite/find.gnu/samefile-p-brokenlink.exp is carried out on OpenBSD
3.9 and on Solaris 10, it fails:

Running
/local/build/bare/findutils-4.3.6/find/testsuite/find.gnu/samefile-same.exp
...
ERROR: tcl error sourcing
/local/build/bare/findutils-4.3.6/find/testsuite/find.gnu/samefile-p-brokenlink.exp.

I am not sure yet what causes this, but I suspect that on this system it is
not possible to create a hard link to a broken symlink, or perhaps it is
possible but it requires the use of an option that we are not using.    

A useful diagnostic would be to attempt these two similar but different shell
commands on the two systems under consideration:-

# 1
rm -rf broken link; 
ln -s nosuchfile broken; 
ln -n broken link; 
ls -il broken link

# 2
rm -rf broken link; 
ln -s nosuchfile broken; 
ln   broken link; 
ls -il broken link

#1 corresponds to what we do now, and #2 passes an -n flag to ln.
