Configuration patches to handle threading and general tuning issues

[John David Anglin]

Hi Loren,

> Thanks for the feedback.  I await HPUX results when possible. 

The rest of the testsuite is still grinding away but here are the
v3 results under HPUX 10.20 with your patch:

1) unix/-threads and unux:

Yes.
