The GNU toolchain is an essential part of the eSDK. It contains the e-gcc compiler, binary utilities, debugger and more. The eSDK adds the other parts, like host and device run-time libraries, BSPs, examples and documentation.
If the GNU toolchain is not found, the SDK build script will halt, asking you to build the toolchain and put it in place before continuation.
