 Note that the PA port generates PA1.1 code unless you explicitly ask for
 PA2.0 code via the -mpa-risc-2-0 runtime switch.
 
 So you really shouldn't need to do anything special to generate PA1.1 code,
 and in fact, by trying to do something special (configure for hppa1.1-hpux)
 you've confused the compiler into thinking it's building cross tools which
 is the root cause of your link time failures.
