Improve Makefile for Windows native builds A Windows Native Build (WNB) can be done: - on Windows, using a recent mingw-w64 g++/clang compiler distributed by msys2, cygwin and others - on Linux, using mingw-w64 g++ to cross compile Improvements: - check for a WNB in a proper way and set a variable to simplify the code - set the proper EXE for a WNB - use the proper name for the mingw-w64 clang compiler - use the static linking for a WNB - use wine to make a PGO cross compile on Linux (also with Intel SDE) - enable the LTO build for mingw-w64 g++ compiler - set `lto=auto` to use the make's job server, if available, or otherwise to fall back to autodetection of the number of CPU threads - clean up all the temporary LTO files saved in the local directory Tested on: - msys2 MINGW64 (g++), UCRT64 (g++), MINGW32 (g++), CLANG64 (clang) environments - cygwin mingw-w64 g++ - Ubuntu 18.04 & 21.10 mingw-w64 PGO cross compile (also with Intel SDE) closes #3891 No functional change
