This patch updates a big comment near the top of dwarfread.c about
the state of dwarf-1 support in gcc compilers and non-gcc compilers.
I am not suggesting that we obsolete dwarf-1 yet, but we're moving
in that direction.
Testing: I built gdb, but I didn't run any tests.
Not quite sure this is obvious, so I'll ask. OK to commit?

If you are looking for DWARF-2 support, you are in the wrong file.
! Go look in dwarf2read.c. This file is for the original DWARF.
! DWARF (also known as DWARF-1) is headed for obsoletion.
! In gcc 3.2.1, these targets prefer dwarf-1:
! i[34567]86-sequent-ptx4* # TD-R2
! i[34567]86-sequent-sysv4* # TD-R2
! i[34567]86-dg-dgux* # obsolete in gcc 3.2.1, to be removed in 3.3

! sparc-hal-solaris2* # TD-R2
! Configurations marked with "# TD-R2" are on Zach Weinberg's list

! targets to be deprecated in gcc 3.3 and removed in gcc 3.4.
! http://gcc.gnu.org/ml/gcc/2002-12/msg00702.html
!
! gcc 2.95.3 had many configurations which prefer dwarf-1.
! We may have to support dwarf-1 as long as we support gcc 2.95.3.
! This could use more analysis.
!
! DG/UX (Data General Unix) used dwarf-1 for its native format.
! DG/UX uses gcc for its system C compiler, but they have their
! own linker and their own debuggers.
!
! Takis Psarogiannakopoulos has a complete gnu toolchain for DG/UX
! with gcc 2.95.3, gdb 5.1, and debug formats of dwarf-2 and stabs.
! For more info, see PR gdb/979 and PR gdb/1013; also:
!
! http://sources.redhat.com/ml/gdb/2003-02/msg00074.html
!
! There may be non-gcc compilers that still emit dwarf-1.
