pkgs/development/libraries/crypto++: fixed build impurity
* Don't build with "-march=native", because the generated binaries won't work reliably on systems with a different CPU. Instead, "--march=i686" is used on x86, and "--march=nocona" an x86_64. Otherwise, "--march" remains unset. * Compile with -O3 instead of -O2. This code is performance-critical. * Don't build with '-g'. svn path=/nixpkgs/trunk/; revision=22785
