Hi,

The AFS filesystem (as in OpenAFS) has some interesting quirks.
Among those is that it only allows hardlinks inside the same directory.

I suggest that the hardlink test should be augmented to test whether
hardlinks between entries of different directories is supported.

'./b2 headers' output head:
