[configure] Explain build host target

build -  which pc you build tool at the first (ex : --build=i686-pc-linux-gnu)

host - which architecture will use after build (ex : --host=arm)

target - which kind of architecture binary file will work after host (ex : --target=arm)


Ex1

--build=i686-pc-linux-gnu (which computer architecture compile first)

--host=arm (which kind of tool package will produce after build process )

--target=arm (which kind of architecture binary file will produce after host process )


Ex2

--build=i686-pc-linux-gnu

--host=arm

--target=mips
