hakre 03b634d114 Prevent fatal error on missing symlink() function in tests 
The testsuite didn't run through for me because the php symlink() function
was missing.

It is only available on Windows Visa/Server 2008 or higher.

This commit fixes the issue by checking if the method exists, and if not,
marks the test as skipped because of a non-matching precondition.
