Didn't knew this, but I went with `.clone` for now.

I'm not sure I understand what the issue with [static pattern rules](http://www.gnu.org/software/make/manual/html_node/Static-Usage.html#Static-Usage) is.
Is it that because the rule is "generic", it may easier lead to mistakes if `$@` et.al. don't get used?
What's the alternative, copying the rule for each target?
