"else" as a variable will never have another value. The POSIX standard
for make reserves variables that start with "." and are all capitalized
for the implementation.
I suppose it's possible that there could be a function $(else ...)
created, but I can't imagine what that would be and it wouldn't conflict
with the variable "else" anyway.
So, you're good.
