testsuite: Fix weak_undefined handling on Darwin

Browse source 
The patch that introduced the weak_undefined effective-target keyword
and corresponding dg-add-options support

commit 378ec7b87a
Author: Alexandre Oliva <oliva@adacore.com>
Date:   Thu Mar 23 00:45:05 2023 -0300

    [testsuite] test for weak_undefined support and add options

badly broke the affected tests on macOS like so:

ERROR: gcc.dg/addr_equal-1.c: unknown dg option: 89 for " dg-add-options 5 weak_undefined "
ERROR: gcc.dg/addr_equal-1.c: unknown dg option: 89 for " dg-add-options 5 weak_undefined "

add_options_for_weak_undefined tries to call an non-existant proc "89".
Even after fixing this by escaping the brackets, two tests still failed to
link since they lacked the corresponding calls do dg-add-options
weak_undefined.

Tested on x86_64-apple-darwin20.6.0 and i386-pc-solaris2.11.
