Libstdc++ configure tweak for crosses

[Daniel Jacobowitz]

There'll be another (more interesting) patch later today, I hope.  Gettext
does need AC_ISC_POSIX, but:
  - it AC_REQUIRE's the macro itself so we don't need to.
  - "gettext" in this context means AM_GNU_GETTEXT, and we don't use that.
  - AC_ISC_POSIX is a link test, which means that it fails if we can't link.
    Right now the whole configure script fails if we can't link, but the
    patch for that will be forthcoming in a few hours.

OK?
