* version.c (banner): New static const variable, complete version
banner text.
(__libc_print_version): Use it, and use __write instead of printf.
* configure.in (sysnames): Don't cache the value, because it
depends only on libc sources. Merge uniquifying third pass into
Implies/parent expansion second pass. Report each unique name as
it is added in partial report string, terminated when finished.
* Makeconfig (sysdep_dir): Move defn before config.status rule that
expands it.
(sysdep-configures): Variable removed.
(config.status): Use its contents directly, tighten up a bit, and
include Implies files.
* elf/dl-open.c (_dl_open) [PIC]: Set PARENT to _dl_loaded if null.
* elf/Makefile ($(objpfx)$(rtld-installed-name)): Make a symlink.
* sysdeps/mach/hurd/dl-sysdep.c (_dl_sysdep_open_zero_fill):
Add comment.
* elf/rtld.c (dl_main): Close _dl_zerofd after mapping deps.
* sysdeps/generic/machine-gmon.h [NO_UNDERSCORES]: Define mcount as
weak alias for _mcount.
* sysdeps/alpha/_mcount.S (mcount): Define as weak alias.
