(libdl-inhibit-o): Variable removed; build all flavors of -ldl.
(rtld-routines): All but rtld, dl-sysdep, and dl-minimal moved to
$(dl-routines).
* elf/dl-lookup.c (_dl_lookup_symbol): Remove magic symbol grokage.
* elf/dladdr.c: Use ELFW(ST_BIND) in place of ELF32_ST_BIND.
* elf/dl-load.c (open_path): Use __ names for open and close. Avoid
using strdup.
(_dl_map_object): Likewise.
(_dl_map_object_from_fd): Use __ names for mmap, munmap, and mprotect.

SYSCALL__ actually generated.

#define __set_errno, as several imported subsystems (eg. BIND) check
that the symbol is defined.

* sysdeps/alpha/memcpy.S: Temporarily remove until I can find a bug
that manifests in GCC.
