Add hppa support.  Still a bit rough around the edges: Some optimisations
(-foptimize-sibling-calls and -freorder-blocks) cause segfaults during build,
so don't include them in -O2 on hppa.  Also, -go is not supported.

requested by and ok brad@ and tested on one of his machines

"Fix" parallel make install by forcing gmake to only run 1 job. It's not
pretty and we would like to have a better fix, but for now it should suffice.
