Re: [PATCH] readelf support for DW_END_default, DW_END_big, DW_END_little

Thanks for submitting this patch.  There was a small problem in that
the code did not handle user specified endian values (ie in the range
0x40 - 0xff).

Whilst looking into this, I also noticed that there are some more DWARF
attributes whose values we do not decode (eg DW_AT_decimal_sign and
DW_AT_defaulted).  Plus there was no testcase for the encoding and 
decoding of these attributes.  So I have taken the liberty of extending
your patch to include these features and checked it in.

Cheers
  Nick
