The build script used the cfg! macro to check the target os, but the "target" in a build script is actually the host. Use the CARGO_CFG_TARGET_OS environment variable instead.
I'm not sure the remaining flags are necessary anymore, but I don't have a macOS/FreeBDS/Linux setup to test it.
If anyone else wants to cross-compile the loader from Windows to Android, you probably have to use ninja with the CMAKE_GENERATOR=Ninja environment variable because MSBuild adds incompatible compiler flags (-fno-exceptions, -std=gnu++17).

Linking the filesystem library is also done correctly upstream now: https://github.com/KhronosGroup/OpenXR-SDK-Source/blob/main/src/cmake/StdFilesystemFlags.cmake
