No. Why would you handle hppa as a secondary or ternary architecture? You need 
the hppa64 cross compiler to bootstrap hppa.  Other architectures require a 
multilib enabled compiler to bootstrap the architecture, however hppa/hppa64 
isn't multilib enabled.  So maybe you don't have this target enabled?  Fyi, 
there is #800729 trying to address this issue properly and not working around 
it. Unfortunately no reply yet.
