add a no-op dsymutil shell script to bypass dsymutil invocation errors in a more simple way (fixes https://github.com/tpoechtrager/osxcross/issues/1)

remove the gcc dsymutil patch (no longer needed)

       [`dsymutil`](http://www.manpagez.com/man/1/dsymutil) (debugger shows only function names).  
   The source code of dsymutil is not publicly available, so it can't be ported to other platforms.  
   But you probably don't want debug symbols anyway if you build on a non OS X system.
