Digging through my emails I found an issue (in the email quoted below) that
I had forgotten about.
The basic issue is that NetBSD puts aio support in librt rather than libc,
but this is only visible when linking statically.
Fortunately, NetBSD is one of the very few platforms on which I have
sufficiently new autotools to run autogen.pl.
The patch below resolves the problem for me.
However, I am not certain if/how this fits with OMPI's standard practices
with regards to configure tests.
