Swig has a compiled in absolute path to its data files, which can be overridden using the SWIG_LIB environment variable: https://github.com/swig/swig/blob/v4.1.1/Source/Modules/main.cxx#L931-L945 This unfortunately means that host-swig misbehaves when used in the SDK, as this points to the ${HOST_DIR}/bin of the build, which may not be available when the SDK is used. The issue was reported upstream but rejected in https://github.com/swig/swig/issues/253, so instead add a wrapper script which calculates a sensible SWIG_LIB relative to the wrapper location unless SWIG_LIB is set, similar to how we do it for E.G. gcc or pkgconf.
