On platforms I've seen, there are 2 sets of libraries but only 64 bit executables
This is what we had for OFED 1.0, OFED 1.1, and I don't see
the reason to change that - adding more executables to install on
production systems will double QA work.

No, by default we build 2 sets of libraries, and only 64 bit execs.
But for your development purposes (I think you mentioned testing user/kernel
context switch) I think we could have --disable-32bit flag to configure to get
only 32 bit userspace.
