Parallelize Link Time Optimization for GCC, CLANG and MINGW This patch tries to run multiple LTO threads in parallel, speeding up the build process of optimized builds if the -j make parameter is used. This mitigates the longer linking times of optimized builds since the integration of the NNUE code. Roughly 2x build speedup. I've tried a similar patch some two years ago but it ran into trouble with old compiler versions then. Since we're on the C++17 standard now these old compilers should be obsolete. closes https://github.com/official-stockfish/Stockfish/pull/2943 No functional change.
