Fixup handling of the .note.ABI-tag section so that it is ARM only,
and so it actually works as intended allowing binaries on ARM to be debugged. -Erik

-/* 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. */
