These already have a cross-reference at the bottom of the file, which
sends users to the more-complete documentation. Ie)

Extensions for Dynamic Analysis
===============================

Use ``__has_feature(address_sanitizer)`` to check if the code is being built
with :doc:`AddressSanitizer`.

Use ``__has_feature(thread_sanitizer)`` to check if the code is being built
with :doc:`ThreadSanitizer`.

Use ``__has_feature(memory_sanitizer)`` to check if the code is being built
with :doc:`MemorySanitizer`.

So I think adding another cross-reference doesn't really add much benefit.
