Allow parallel install
When trying 'make -j{n} install', you may occasionally run into trouble because to sub-targets (install_dev and install_runtime) try to install the same shared libraries. That makes parallel install difficult. This is solved by dividing install_runtime into two parts, one for libraries and one for programs, and have install_dev depend on install_runtime_libs instead of installing the shared runtime libraries itself.
