ld einfo positional arg support

ld einfo positional arg support

To allow translators to reorder values in translated strings.  This
should mean that all binutils messages now have support for
reordering.

Note to translators:  Not all % letters take arguments, so for example
the following only has two arguments, the two %s strings.
"%P%F: output format %s cannot represent section called %s: %E\n"

You could reorder this if you liked to:
"%P%F: %E: section %2$s cannot be represented in output format %1$s\n"

einfo lacks support for flags, field width, precision and length
modifier (apart from %ld and %lu) so don't try to use them in
translations.  Both ld and bfd lack support to use a positional arg
twice.  These features could be added if needed..

	* ldmisc.c (vfinfo): Support up to 9 positional args.
