source code used to generate bad DWARF

DW_TAG_friend is first documented in DWARF4 and should have
a DW_AT_friend attribute, not the attributes listed here
(attributes as shown by dwarfdump -i -M).

< 4><0x00000dd4>          DW_TAG_friend
        DW_AT_type                  <0x00000272> <form DW_FORM_ref4>
        DW_AT_data_member_location  DW_OP_plus_uconst 0 <form DW_FORM_block1>
        DW_AT_accessibility         DW_AT_accessibility has a bad form.


This is 2.9.    The compile command was clang++ -O0 -g const.cpp
on Ubuntu 11.10 x86_64.  And on Ubuntu 11.10 x86.
