 If the above make command fails please use "make clean pristine" and then remove and remake the build directory. This will clean up and prepare the environment for another attempt. A common reason for failure on virtual machines is lack of RAM (if you don't have enough RAM you may get an error like this "recipe for target 's-attrtab' failed"). Otherwise, if all goes well in about 30 to 60 minutes the compiler will be ready and we will move on to the next steps.
