As a single datapoint, I've been relying on the fact that make check 
doesn't rebuild. Sometimes I work on underpowered machines and will 
continue to reformat my code after the .o file has been built. Relinking 
can take more than five minutes. I do not like this change, but my 
argument is also rather silly, per http://xkcd.com/1172 .

Now, it seems to recompile the project just like a "make" would and then run the tests. Is it just me or are others seeing this too? Is this a intended behavior change?
