yes please!

I can never remember all the components that I need to disable from 
binutils to get as quick a compilation as possible. I am still not sure 
if I did disable everything or if copying my previous configure run 
isn't accidentally building some parts unnecessarily. I'm not sure if I 
personally like the `-components` suffix, but I don't have any better 
suggestions.
