Subject: [PATCH] crtend.asm: Include "auto-host.h".

        * config/ia64/crtend.asm: Include "auto-host.h".
        [HAVE_INITFINI_ARRAY]: Invoke __do_global_ctors_aux via .init_array.
        * config/ia64/crtbegin.asm: Similarly.
        * config/ia64/t-ia64 (crtbegin.o): Include from current directory.
        (crtend.o, crtbeginS.o, crtendS.o): Likewise.

        * aclocal.m4 (gcc_AC_INITFINI_ARRAY): New.
        * configure.in: Use it if --enable-initfini-array not specified.
        * doc/install.texi (Configuration): Document --enable-initfini-array.
        * configure, config.in: Rebuild.
