The primary motivator here is in the third patch, allowing any
threads to be created. Previously I had written off crashes
using threads as lack of MTTCG support without really digging
into it deeper. Ho hum.
But in the process of looking for the root cause, Helge found
two other things that are incorrect for hppa.
For the purposes of 2.10, I believe the first patch is the way
forward. However, if desired, in the interest of stage1-ness,
I'm willing to rewrite the first patch to use ifdef TARGET_HPPA,
and so not affect other targets.

I beg your pardon, we do -- they're just named confusingly. target_old_sigaction/target_rt_sigaction vs target_sigaction.
