Hello,

This adds a config pattern to match hppa*-*-*.  It configures a very 
simple PA risc target.  The target doesn't include SOM support (ya!).

The build then barfs in hppa-tdep.c as that file is trying to suck in 
system headers (a big NO NO!).

If anyone is looking to multi-arch HPPA then, I think, getting this 
target to build will make a very good starting point.

committed,
Andrew
