This commit introduces tools/update_glibc.zig to update the start files for next time. Some notable changes in recent glibc: * abi-note.S has been changed to abi-note.c but we resist the change to keep it easier to compile the start files. * elf-init.c has been deleted upstream. Further testing should be done to verify that binaries against glibc omitting elf-init.c still run properly on oldel glibc linux systems. Closes #4926
