Don't rely on it:

bash$ eval "hi=ho `echo \"; echo $hi\"`"
ho

There is enough quoting going on in the makefile that I certainly can't be
sure of when the shell will think it should or shouldn't perform expansions,
without testing to see, and so it is wise to force it. Defensive programming.

But yes, I was wrong in the quote.
