It's possible.  Neither the ultimate host system nor the filesystem
was specified.

Preferably yes, File::Find should handle it automatically.  But it's not
really a per-platform question, it's per-filesystem, like case sensitivity
of filenames.  Anything we do statically at build time will suffer both
false positives and false negatives.  Really the reliability of the
nlink==2 trick ought to be advertised through pathconf(2), but it isn't.
In the absence of that, there are still some ways we could autodetect it.
statfs(2) on Linux advertises a `filesystem type', and we could use that
to determine whether nlink is reliable for known types.
