* Special ".note" entry to tag an Android binary and specify the ABI version.
*
* For all arches except sparc, gcc emits the section directive for the
* following struct with a PROGBITS type. However, the section should be
* of NOTE type, according to the Generic SysV ABI spec.
*
* Unfortunately, there is no clean way to tell gcc to use another section type,
* so this C file (or the C file that includes it) must be compiled in multiple
* steps:
*
* - Compile the .c file to a .s file.
* - Edit the .s file to change the 'progbits' type to 'note', for the section
* directive that defines the .note.ABI-tag section.
* - Compile the .s file to an object file.
*
* These steps are done in the invididual Makefiles for each applicable arch.
