Only add a symlink to the repository if both the filesystem and

$ zip -y infozip-symlinks.zip textfile symlink
Hm. Do some implementations of "unzip" not support symlinks, or is
the problem that some systems build Info-ZIP without the SYMLINKS
option?
The unzip supplied with NetBSD 6.0.1, which is based on libarchive,
doesn't support symlinks. It creates a file with the link target path
as its only content for such entries.
I assume that Info-ZIP is compiled with the SYMLINKS option on all
platforms whose default filesystem supports symbolic links. Except on
Windows perhaps, where it's complicated.
For the test script there is no difference: If we don't have a tool to
verify symlinks in archives, we better skip that part.
