  SVN rev 197931 on 2009-10-10 15:27:10Z by kib
  
  Calculate relocation base for the main object, and apply the relocation
  adjustment for all virtual addresses encoded into the ELF structures of
  it. PIE binary could and should be loaded at non-zero mapbase.
  
  For sym_zero pseudosymbol used as a return value from find_symdef()
  for undefined weak symbols, st_value also should be adjusted, since
  _rtld_bind corrects symbol values by relocbase.
