    csu: Find the main pointer through the GOT
    
    Use the Global Offset Table to find the location of main in crt1. With
    lld the old code would point to main@plt, however ld.bfd fails to link
    when main is in a shared library.
    
    Fix this by using the GOT address to find main as it works with both
    lld and bfd.
