Log Message:
make: for recursive variables in commands, print location

Print the approximate location based on the last command that has been
defined for the target.  It would be possible to get more detailed
location information by counting the number of commands of the target,
but that would get messy due to .USEBEFORE, .USE and .DEFAULT, and
still, this is an edge case, so don't waste too much code for it now.
Having this hint about the location is more helpful than just a plain
"Variable X is recursive" without any further details.
