  Log:
  Don't match executables with ELFOSABI_NONE against the brand list.
  For binaries without matching brand, try to match PT_NOTE header
  of type 1 (which is equal to .note.ABI-tag as section).
  
  Implement matching for FreeBSD, the up-coming DragonFly and Linux
  ABI tag.
  
  This implementation has some known limitations:
  - only one PT_NOTE header of type 1 is checked (the last)
  - the PT_NOTE header has to be part of the first page
  - ELF branding is prefered, no further matching is done (prevents multiple
    ABI emulations for the same ELF OS ABI)
