Commit ID 6d6267c378aa0aa354e203e5025361d9a4e0d449

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.
