I also hit that loop on DragonFly this month when I set 
TOOLS_PLATFORM.tar=tar (without full path).

As for the "echo", I see that is a problem. And the bogus wrapper is 
created. This problem exists on other platforms.

The reason nobody sees it is because their shell provides "echo" builtin.

Tell us about your BusyBox /bin/sh shell. Does it have echo builtin?

Maybe the pkgsrc tools framework should not create a wrapper unless the 
tool has a full path.

Do you also have the problem for [, false, test and true?
