This will be useful to define a NULL-terminated array inside a function
call.

Currently, string arrays passed to match() are defined in separate
places:

    static const char *const init_sections[] = { ALL_INIT_SECTIONS, NULL };
    static const char *const text_sections[] = { ALL_TEXT_SECTIONS, NULL };
    static const char *const optim_symbols[] = { "*.constprop.*", NULL };

            ...

            /* Check for pattern 5 */
            if (match(fromsec, text_sections) &&
                match(tosec, init_sections) &&
                match(fromsym, optim_symbols))
                    return 0;

With the new helper macro, you can list the patterns directly in the
function call, like this:

            /* Check for pattern 5 */
            if (match(fromsec, PATTERNS(ALL_TEXT_SECTIONS)) &&
                match(tosec, PATTERNS(ALL_INIT_SECTIONS)) &&
                match(fromsym, PATTERNS("*.contprop.*")))
                    return 0;
