My colleague saw this warning in his cmake output when he was testing a 
toolchain file. After seeing it, he didn't even try the build, he just told 
me the toolchain file was broken. 

I told him about this warning being bogus, he ran the build, and of course 
it worked :). 

Is there any reason this variable shouldn't be special-cased in the unused 
variable handling? If the special case is spelled correctly, it should be 
fine.

Thanks,

Steve.
