Windows: Use response files to specify link libraries for GNU tools
Work around the command-line-length limit by using an @linklibs.rsp response file to pass the flags for link libraries. This allows very long lists of libraries to be used in addition to the existing support for passing object files via response file. Suggested-by: Peter Keuschnigg <peter.keuschnigg@pmu.ac.at>
