I've now completed the testsuite with your patch installed
and I'm sorry to report something very weird.

A considerable number of tests failed.  Several failures
appear to be caused by deficencies in the ancient binutils
2.11.2 used by NetBSD.

Comparing these results with the previous run (without your
patch installed) reveals lots of changes (see the diff below).
What's shocking is that, overall, the number of failures
actually *increased*!

I've not yet analyzed any of these failures because I want
to try bootstrapping again from a combined tree in order
to use GNU as/ld.
