Make two different binaries for ar and ranlib, instead of
distinguishing them at run time using argv[0].
(Old behavior is still available if you "make ar_with_ranlib",
but it is not the default.)
* ranlib.sh (new): An alternative one-line
shell implementation of ranlib.
MISSING_VFPRINTF, and don't confuse the issue with NO_VARARGS.
* objdump.c (dump_headers): Trivial output format change.
* objdump.c (display_info): Loop over integers, not enums,
to appease old compilers.
