#507 elfdump -n omits notes it does not understand

[Ed Maste]

elfdump generally dumps ELF contents in a low-level, raw format. It only handles a limited set of ELF notes though, omitting all others. It should display all ELF note data.

E.g.

% readelf -n /bin/ls

Notes at offset 0x00000218 with length 0x00000030:
  Owner          Data size       Description
  FreeBSD        0x00000004      NT_FREEBSD_ABI_TAG
  FreeBSD        0x00000004      NT_FREEBSD_NOINIT_TAG

% elfdump -n /bin/ls
%

Also Solaris-style output isn't quite as expected -- e.g. from SmartOS (Illumos):

# elfdump -n /bin/ld
