[PATCH 1/3] Remove gdbtypes special case from init.c rule

[Tom Tromey <tom@tromey.com>]

The rule to make init.c has a special case for gdbtypes, with a long
explanatory comment.  All of this is obsolete, as the globals referred
to by the comment no longer exist.  This patch simplifies the rule.

 # FIXME: There is a problem with this approach - init.c may force
 # unnecessary files to be linked in.
 
-# FIXME: cagney/2002-06-09: gdb/564: gdb/563: Force the order so that
-# the first call is to _initialize_gdbtypes (implemented by explicitly
-# putting that function's name first in the init.l-tmp file).  This is
-# a hack to ensure that all the architecture dependant global
-# builtin_type_* variables are initialized before anything else
-# (per-architecture code is called in the same order that it is
-# registered).  The ``correct fix'' is to have all the builtin types
-# made part of the architecture and initialize them on-demand (using
-# gdbarch_data) just like everything else.  The catch is that other
-# modules still take the address of these builtin types forcing them
-# to be variables, sigh!

 # NOTE: cagney/2003-03-18: The sed pattern ``s|^\([^ /]...'' is
 # anchored on the first column and excludes the ``/'' character so
 # that it doesn't add the $(srcdir) prefix to any file that already
