mklib.glide changes

There seems to be a problem with libc5 showing up. Here is what you do to 
make it use glibc when you recompile:


In the file 'mklib.glide':

  # If we're making the libMesaGL.so file then also link in the Glide libs.
  # The -L/usr/i486-linux-libc5/lib option is specified so that licb5 is
  # used on RedHat 5.x systems.  This helps to fix Quake problems.  This
  # tip comes from Emil Briggs (briggs@tick.physics.ncsu.edu).  Thanks!
  if [ $LIBRARY = "libMesaGL.so" ] ; then
    GLIDELIBS="-L/usr/local/glide/lib -lglide2x -L/usr/i486-linux-libc5/lib -lm"
  fi

Replace those lines with:

  GLIDELIBS="-L/usr/local/glide/lib -lglide2x -lm"
