Apologies for posting in Dev instead of Support at first. I placed my 
response to your questions in-line. Also I am not entirely sure what you 
mean by leaving -gnu off the end of my target triplet? Should it be 
i686-cm-linux-gnu-gcc? Sorry if that's a dumb question, but I'm 
obviously new at this!
