(svn r7959) [Configure] -Fix: OS2-gcc needs to get stripping via gcc, because it needs to be feed to emxbind at link-time.

emxbind changes 'emx a.out' format to 'LX for OS/2 (MS-DOS)'. After this, all gcc and binutils tools for emx can no longer read the binary.
  Therefor emxbind needs to do the stripping while converting it. Logic, aint it? :)
