build-id is in a note being both a section and a segment.  GDB currently reads
it as a section but this can be changed.

Program Headers:
  Type           Offset   VirtAddr           PhysAddr           FileSiz  MemSiz   Flg Align
[...]
  NOTE           0x000254 0x0000000000400254 0x0000000000400254 0x000044 0x000044 R   0x4
[...]
Notes at offset 0x00000274 with length 0x00000024:
  Owner         Data size       Description
  GNU           0x00000014      NT_GNU_BUILD_ID (unique build ID bitstring)

It was designed by Roland McGrath exactly this way so that in all cases of
debug info stripping build-id remains in the main executable.  Otherwise
build-id would be useless.


Thanks,
Jan
