Is there any case where gcc on windows will use the windows quoting style?

If the answer is no, and I assume GNU ar is the same, then perhaps the solution is revert https://reviews.llvm.org/D69665 instead and have all the llvm tools except clang-cl default to the GNU style.

> The fact that any clang can be used for any target, blurs the distinction, as an msys2/mingw based clang both can be used for targeting wasm (where the build tools might expect to use windows style quoting) and for general mingw target things (where the build tools out of tradition expects to use unix style quoting in rsp files).
