I think this is a good idea, just a minor comment:

> +# We use the same hardening flags for C.  We must check that each flag
> +# is supported by both compilers.
> +AC_DEFUN([check_cc_flag],
> + [AX_CHECK_COMPILE_FLAG([$1], [$2], [$3], [-Werror $4])])
> +AC_DEFUN([check_link_flag],
> + [AX_CHECK_LINK_FLAG([$1], [$2], [$3], [-Werror $4])])

auto* function names are generally uppercase, so uppercase those too,
please?
