In this silly example it is maybe obvious but I have lost hours tracking
down bugs due to this.
You add a new target and suddenly someting unrelated breaks.
What happens is that make consider the assignment a command due to the leading
tab - and because is follows a target (or other commands).
I hope this makes it clear why many makefiles in the kernel uses tabs for
indent.
This is also a good reason why not to indent assignments in Makefiles by
full tab stops. A smaller indent can't be scrambled this way.
