Untested proposed fix

This untested patch fixes the issue for me on a cross-compiler.  It
would be great if someone who is set up to run the testsuite on a
platform with multiple address spaces or a simulator of one could test
it a bit.

My plan is to discuss this with maintainers next week and if they like
the approach, give it a formal bootstrap and test run on x86_64 and
submit shortly thereafter if everything goes fine.
