* config/tc-hppa.c (hppa_fix_struct): Add new "segment" field.

Browse Source 
(hppa_fix_new): Initialize segment field.
        (md_apply_fix): Do nothing for pc-relative fixup which involves
        crossing a segment boundary.
        (pa_procend): Undefine the current label after handling .PROC
        and .PROCEND directives.
        (dummy_symbol): Make type "symbolS *".  Change references as
        appropriate.
