Fixing once again the ld-wrapper.sh script. I put it in a gcc-wrapper apart, to be removed
on the next stdenv-updates. This would fix the build for many cmake packages, although that requires updating the stdenv in those for its gcc to use this 2nd wrapper. I updated paraview and avidemux. I can't recall now more packages with problems, but I was quite sure there were. If anyone sees a cmake-built package with the result binaries lacking some rpaths, then try this wrapper. svn path=/nixpkgs/trunk/; revision=20669
