    kernel ELF: Map PIE binaries at non-zero or specified address
    
    From FreeBSD:
    svn 197933 (10 OCT 2009)
    svn 197934 (10 OCT 2009)
    svn 198202 (18 OCT 2009)
    
    By default, map PIE binaries to a non-zero address.  The specified
    default address was determined by FreeBSD by examining ld to see where
    non-relocable binaries get put normally.
    
    The binary relocation will not happen if the ET_DYN binary already has
    a non-zero base address specified.
    
    Also cleaned up some whitespace issues, and took some alignment checks
    from FreeBSD.
