Only add a symlink to the repository if both the filesystem and
unzip support symlinks.  To check the latter, add a ZIP file
containing a symlink, created like this with InfoZIP zip 3.0:

	$ echo sample text >textfile
	$ ln -s textfile symlink
	$ 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.
