Updating top-level files for automake

As part of the transition, libstdc++ will be going to automake 1.7,
for its features and bugfixes. However, trying to configure using this
version results in problems, because $srcdir/missing is too old.
I updated missing, install-sh, and mkinstalldirs to the versions which
aclocal/automake would install in a new project. There do not appear
to be any backward incompatabilities, so directories which have not yet
converted to newer autoconfs, and/or are not using automake at all, should
have no difficulties.
Nevertheless, please look these diffs over. I'll continue to use them in my
local tree as I wrestle with autoconf. If you agree that these patches are
safe, I'll send them to gcc-patches for a wider audience and discussion.
(I tend to think of these files like config.{guess,sub}, where they can
simply be updated as needed, but...)
