[Bug symtab/10002] New: extern optimized out symbols print: Address of symbol is unknown.

["jan dot kratochvil at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

Testcase:
------------------------------------------------
extern int missing;

int
main (void)
{
  return 0 && missing;
}
------------------------------------------------
gcc -o kfail kfail.c -Wall -g
gcc-4.3.2-7.x86_64 (Fedora 10)

produces:
 <1><55>: Abbrev Number: 4 (DW_TAG_variable)
    <56>   DW_AT_name        : (indirect string, offset: 0x66): missing	
    <5c>   DW_AT_type        : <0x4e>	
    <60>   DW_AT_external    : 1	
    <61>   DW_AT_declaration : 1	

and GDB prints:
GNU gdb (GDB) 6.8.50.20090324-cvs
(gdb) p missing
Address of symbol "missing" is unknown.

It should print:
(gdb) p missing
$1 = <value optimized out>

Filing only to get a number for KFAIL, it was discussed at:
