>Description:
If you've overridden ${TAR} (say, to add other options), the invocation
in the port Makefile has to be ${TAR} -options. If the Makefile uses
${TAR} options (i.e., no hyphen), tar freaks out.

Attached patch simply adds hyphens before the options, and allows ${TAR}
to be overridden in, for example, /etc/make.conf.
>How-To-Repeat:
	
>Fix:

It's been a very long time since I've sent a PR. If I'm putting the patch
in wrong, I apologize in advance.
