    hppa: Fix missing call to __feraiseexcept (BZ 34306)
    
    The feupdateenv function is supposed to raise exceptions after
    installing the environment represented by its envp argument.
    This was accidentally missed on hppa.
    
    The failure to raise exceptions was noticed by the failure of
    the math/test-narrowing-trap test.
