Get rid of the dependency on intel-cmt-cat library and rdt helper binaries written in C. Significantly simplifies the build procedure. Implements minimal support (in assembler) for getting the raw data from the CPUID instruction. Also, implement a stub so that the code works on other architectures than amd64, too.
