It doesn't seem to be needed, and this makes the build work for environments where MinGW-w64 cross-toolchains get installed someplace else (e.g. macOS with Homebrew to /usr/local).

Quick start on a Linux build host:
# Install Meson and a recent build of MinGW-w64, then:
$ meson --cross cross-build-32.txt _build32
$ ninja -C _build32
$ meson --cross cross-build-64.txt
$ ninja -C _build64
Building on MSYS2 is also possible; consult Meson documentation for details.
Additional documentation will be forthcoming.
