    Cygwin: Makefile: build new-cygwin1.dll in a single step
    
    The complicated build routine was only required because we needed
    the .cygheap section at the end of the file, and the debug sections
    broke this.  Now that the cygheap is out of the way, we really don't
    have to do this anymore, and the build can just generate a DLL with
    integrated debug info.
