/* Define an ELF note identifying the operating-system ABI that the

   executable was created for.  The ELF note information identifies a

   particular OS or coordinated development effort within which the

   ELF header's e_machine value plus (for dynamically linked programs)

   the PT_INTERP dynamic linker name and DT_NEEDED shared library

   names fully identify the runtime environment required by an

   executable.

   The general format of ELF notes is as follows.

   Offsets and lengths are bytes or (parenthetical references) to the

   values in other fields.

offset	length	contents

0	4	length of name

4	4	length of data

8	4	note type

12	(0)	vendor name

		- null-terminated ASCII string, padded to 4-byte alignment

12+(0)	(4)	note data,

   The GNU project and cooperating development efforts (including the

   Linux community) use note type 1 and a vendor name string of "GNU"

   for a note descriptor that indicates ABI requirements.  The note data

   is four 32-bit words.  The first of these is an operating system

   number (0=Linux, 1=Hurd, 2=Solaris, ...) and the remaining three

   identify the earliest release of that OS that supports this ABI.

   See abi-tags (top level) for details. */
