This fixes a bug where GCC++ on Ubuntu 18.04 creates failing executables compared to GCC++ on 16.04 and clang++. While creating function names on Ubuntu 18.04, dl_phdr_info seems to provide a non-zero value for dlpi_addr on initial iteration, and an empty string in dlpi_name. This is causing failure when linking with g++, since the empty string prevents the kernel function from being loaded. Clang++ and GCC on UB16 provide a zero value for dlpi_addr. To fix this, we need to verify both addr and name exists, so that /proc/self/exe can be properly loaded.
