[Bug target/35514] New: Gcc shoud generate symbol type for undefined symbol

[hjl dot tools at gmail dot com]

Gcc doesn't generate symbol types for undefined symbol on ELF targets:

bash-3.2$ cat x.c
extern void foo() __attribute__((weak,visibility("hidden")));
extern int puts( char const* );
int main()
{
        foo ? foo() : puts( "foo == null, skipped." );
        return 0;
}
bash-3.2$ gcc -c x.c
bash-3.2$ readelf -s x.o

Symbol table '.symtab' contains 12 entries:
   Num:    Value          Size Type    Bind   Vis      Ndx Name
     0: 0000000000000000     0 NOTYPE  LOCAL  DEFAULT  UND 
     1: 0000000000000000     0 FILE    LOCAL  DEFAULT  ABS x.c
     2: 0000000000000000     0 SECTION LOCAL  DEFAULT    1 
     3: 0000000000000000     0 SECTION LOCAL  DEFAULT    3 
     4: 0000000000000000     0 SECTION LOCAL  DEFAULT    4 
     5: 0000000000000000     0 SECTION LOCAL  DEFAULT    5 
     6: 0000000000000000     0 SECTION LOCAL  DEFAULT    6 
     7: 0000000000000000     0 SECTION LOCAL  DEFAULT    9 
     8: 0000000000000000     0 SECTION LOCAL  DEFAULT    8 
     9: 0000000000000000    43 FUNC    GLOBAL DEFAULT    1 main
    10: 0000000000000000     0 NOTYPE  WEAK   DEFAULT  UND foo
    11: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT  UND puts
bash-3.2$ 

ELF linker needs symbol type to properly issue diagnostic message.
