Tom Lane 5fcb210e8d Fix configure's AC_CHECK_DECLS tests to work correctly with clang.
The test case that Autoconf uses to discover whether a function has
been declared doesn't work reliably with clang, because clang reports
a warning not an error if the name is a known built-in function.
On some platforms, this results in a lot of compile-time warnings about
strlcpy and related functions not having been declared.

There is a fix for this (by Noah Misch) in the upstream Autoconf sources,
but since they've not made a release in years and show no indication of
doing so anytime soon, let's just absorb their fix directly.  We can
revert this when and if we update to a newer Autoconf release.

Back-patch to all supported branches.
