The DWARF and DWARF2 debugging formats don't work on Solaris 2.6 sparc.
This bug occurs in both GCC 2.8.0 and GCC 2.8.1-980214.
This breaks -ggdb. The stabs format still works, so the workaround
is to use -gstabs+ instead of -ggdb.

Perhaps -ggdb should imply -gstabs+ instead of -gdwarf-2 on Solaris
until DWARF2 is made to work?

Here are the symptoms of the problem:

$ cat t.c
main() { return 0; }
$ gcc -g t.c
$ gcc -gstabs+ t.c
$ gcc -gdwarf+ t.c
