[phobos] Mac OS X unit tests failing

[Jonathan M Davis]

For some reason, the unit tests on Mac OS X are failing for std.file.symlink. 
They pass just fine on Linux and FreeBSD, but the the Mac isn't so happy with 
them.

Does anyone with a Mac have time to look at it? It tries to create a symlink 
to /usr/include and verify that it worked, and it claims that the file exists 
after calling symlink, but it also claims that it's not a symlink (hence the 
failure). I have no access to a Mac, and so I can't do anything to fix it. We 
can disable to the failing unit tests if we have to, but we should really fix 
the issue rather than hiding the failing tests.
