Replace @PLT with @GOTPCREL(%rip) in call
Since __libc_start_main is called very early, lazy binding isn't relevant here. Use indirect branch via GOT to avoid extra branch to PLT slot. [BZ #19745] * sysdeps/x86_64/start.S (_start): __libc_start_main@PLT with *__libc_start_main@GOTPCREL(%rip) in call.
