To speed up the build process, you can make use of parallel execution of ma= ke utility with the following command: make -j , where=A0 N is the number of parallel jobs, determined by the = number of CPU cores available in your system. To determine the number of CPU cores in your system, read http://www.cyberc= iti.biz/faq/linux-get-number-of-cpus-core-command/ Also, read https://gcc.gnu.org/install/ - for more info on building GCC fro= m source.
