Bug description:SplFileInfo::getLinkTarget fails

Description:
------------
SplFileInfo::getLinkTarget
(http://www.php.net/manual/en/splfileinfo.getlinktarget.php) does not seem
to work at all. It fails with a "Unable to read link <symlink name>, error:
Invalid argument" message. Reproduced on 5.3.8 and 5.3.10-dev snapshot
(201201312030) but works on 5.2.17.

This similar but not quite the same as #51804
(https://bugs.php.net/bug.php?id=51804)

Test script:
---------------
touch('testfile');
symlink('testfile', 'testlink');
$f = new SplFileInfo( 'testlink' );
printf( 'readlink: %s'.PHP_EOL, readlink( $f->getPathname() ) );
printf( 'SplFileInfo::getLinkTarget: %s'.PHP_EOL, $f->getLinkTarget() );

Expected result:
----------------
readlink: testfile
SplFileInfo::getLinkTarget: testfile

Actual result:
--------------
readlink: testfile

Fatal error: Uncaught exception 'RuntimeException' with message 'Unable to
read link testlink, error: Invalid argument' in
/home/aheadley/Desktop/testing/test.php:6
Stack trace:
#0 /home/aheadley/Desktop/testing/test.php(6):
