Command line is limited in length on windows so meson/ninja puts it in a response file and passes that to the linker instead. Only problem is, ninja -v displays only the part of the command line where it tells link.exe where the response file is, not what's in the response file. So I just had the script print it. Care must also be taken for the script to properly fail if ninja fails, but not before the command line is printed.
Also add /GL and /LCTG to msvc command lines because they can't hurt. Right?
