is the system root path to use.
This option overrides any system root path that is automatically detected. It can be used as part of a manual approach to configuring the tools for use with ARM Linux if you want to use a different path to your normal system root path.
The system root path is the base path that libraries and header files are normally found from. On a standard Linux system, this is typically the root of the file system. In a cross compilation GNU toolchain, it is usually the parent directory of the GNU C library installation. This directory contains the lib, usr/lib, and usr/include subdirectories that hold the C libraries and header files.
