Build: Fix the combination of --disable-xzdec --enable-lzmadec.

Browse source 
In this case "make install" could fail if the man page directory
didn't already exist at the destination. If it did exist, a
dangling symlink was created there. Now the link is omitted
instead. This isn't the best fix but it's better than the old
behavior.

# FIXME: If xzdec is disabled, this will create a dangling symlink. # Create the symlink lzmadec.1->xzdec.1 only if xzdec.1 was installed.
# This is better than creating a dangling symlink, especially
# because creating the link may fail due to the directory being missing.

# FIXME: The correct solution would be to install xzdec.1 as lzmadec.1
# but I don't know what is the sane way to do it and since this is a bit
# unusual situation anyway, it's not that important.
