The patch that introduced the weak_undefined effective-target keyword
and corresponding dg-add-options support
commit 378ec7b87a5265dbe2d489c245fac98ef37fa638
Author: Alexandre Oliva <ol...@adacore.com>

[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.
Committed to trunk.
