Thanks. I'm adding this tweak to match the usual coding style: Initialize the
HAVE_STRUCT_RANDOM_DATA variable to 1, and set it to 0 when we see it's
missing. This looks pointless in this case, but is a useful convention when a
HAVE_* variable needs to be set to 0 at various places, for various possible
reasons (see e.g. REPLACE_CLOSE and gl_REPLACE_CLOSE).

        * m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS): Set default of
        HAVE_STRUCT_RANDOM_DATA to 1.
        (gl_STDLIB_H): Simplify.
