Pass include directories with response files to GNU on Windows

The GNU 4.x toolchain on MinGW (and therefore MSYS) allows compiler
options to be passed via response files.  Use this to pass include
directory -I options.  This allows the include file search path to be
very long despite shell and mingw32-make command line length limits.
