The person who built the compiler that runs on my machine built it on a machine just like mine, an 'i486-linux-gnu' (build), and intended for it to run on a machine like his/mine: the same i486-linux-gnu (host), and he meant for this compiler he was building for me, to emit executables that targeted my very machine, so that when I compile programs, they will be able to run on a host that is i486-linux-gnu. Therefore he made the compiler target i486-linux-gnu.
