toolchain folders and content

Hi, I am using the linaro tolchain to create a root-filesystem for an embedded Linux system. I would like to copy the essential include files and libraries(libc) from the toolchain to the rootFS of the embedded system.

Is there any explanation of the folder structure of the toolchain so I know which folder to copy? How do I know which files to copy and where those files are located in the toolchain?

Thanks, Robert
