Both in config.h and llvm-config.h it is defined as
"x86_64-w64-mingw32". I also had a brief look at
LLVM/lib/Support/Triple.cpp and can't find anything that stands out
(except for the fact that the *-w64-* vs *-pc-* isn't handled, but as
far as I know, that's only used by GCC itself to differentiate certain
low-level aspects like library/crt/header locations when it builds
itself, nothing Clang needs to worry about yet).
