gbl-ctors.h: Lose HAVE_ATEXIT.

Browse source 
* gbl-ctors.h: Lose HAVE_ATEXIT.  Don't define ON_EXIT.
	* libgcc2.c: Lose obsolete defn of WEAK_ALIAS.
	(__bb_init_func, __bb_init_prg): Use atexit instead of ON_EXIT.
	(__do_global_dtors): Likewise.  Don't mess with _exit_dummy_decl.
	(atexit, exit): Simplify.
	* tm.texi: Document NEED_ATEXIT and ON_EXIT.  Remove HAVE_ATEXIT.
	* config/lots: Remove defns of HAVE_ATEXIT.

@item HAVE_ATEXIT
@findex HAVE_ATEXIT
Define this if the target system supports the function
@code{atexit} from the ANSI C standard. If this is not defined,
and @code{INIT_SECTION_ASM_OP} is not defined, a default
@code{exit} function will be provided to support C++.
@item NEED_ATEXIT
@findex NEED_ATEXIT
Define this if the target system lacks the function @code{atexit}
from the ANSI C standard. If this macro is defined, a default definition
will be provided to support C++. If @code{ON_EXIT} is not defined,
a default @code{exit} function will also be provided.
@item ON_EXIT
@findex ON_EXIT
Define this macro if the target has another way to implement atexit
functionality without replacing @code{exit}. For instance, SunOS 4 has
a similar @code{on_exit} library function.
The definition should be a functional macro which can be used just like
the @code{atexit} function.
