Surely it's just an accident that you've seen it only for ELC, as the 
problem can occur if 'make' executes any two $(info ...)s at about the 
same time.

How badly does it occur for you? For me, it's only the first line (when 
many 'makes' start in parallel, which is a glitch I can easily ignore.

If it's a real annoyance please try the attached patch, which should fix 
the problem for the AM_V_ stuff at the cost of appending annoying empty 
lines with current and older GNU make. (Which annoyance do you prefer? 
:-) You'll need to run './config.status' after applying the patch.
