Brendan Roy 4fc67fe44a tpl: Add errorf template function 
Add template function that will build a string from the given format
string and arguments, then log it to ERROR. This has an intended
side-effect of causing the build to fail, when executed.

errorf will evaluate a format string, then output the result to the ERROR log. This will also cause the build to fail.
