Make doesn't put any space between variables when concatenating them.

If you are seeing spaces above that must mean that you have whitespace
at the end of the variable setting line for FOO.  Any trailing
whitespace on a variable definition is considered part of the value.

Either get an editor that will allow you to strip trailing whitespace
(Emacs can do this), or start using the $(strip ...) function
religiously.
