worked for me, except for a problem with redefinition of struct dirent64.
I hacked that out of /opt/palinux/hppa-linux/include/linux/dirent.h to
temporarily get round it.

I havn't checked the binary works.  You might have to remove a chunk
of code from strace/defs.h, depending on how new your glibc is.  With
a new glibc you need to remove the following block:

  /* Hack until I figure out why we don't call ptrace in glibc, rather
   * than the system call direct.
   */
  static inline long raw_ptrace(int req, pid_t pid, void *addr, long data)
  {
          long res, ret;
  
          if (req > 0 && req < 4)
                  data = (long)&ret;
          res = ptrace(req, pid, addr, data);
          if (res >= 0 && req > 0 && req < 4) {
                  errno = 0;
                  return ret;
          }
          return res;
  }
  
  #define ptrace raw_ptrace
