    Fix hppa-linux pr22269-1 fail

    Adds UNDEFWEAK_NO_DYNAMIC_RELOC in the rest of places needed in this
    file, reduces dynamic relocations in a number of cases, and removes
    some bogus code that was attempting to handle dynamic common symbols
    specially.

        PR 22269
        * elf32-hppa.c (elf32_hppa_check_relocs): Move SEC_ALLOC test to
        ensure non_got_ref is not set due to debug references.
        (elf32_hppa_adjust_dynamic_symbol): Tidy plabel handling.  Use
        SYMBOL_CALLS_LOCAL and UNDEFWEAK_NO_DYNAMIC_RELOC when determining
        need for a plt entry.
        (allocate_dynrelocs): Similarly for got entries.  Tidy code discarding
        dynamic relocs when pic.  Remove bogus code attempting to handle
        commons.
        (elf32_hppa_relocate_section): Similarly.  Delete resolved_to_zero
        and simplify.
        (elf32_hppa_finish_dynamic_symbol): Use UNDEFWEAK_NO_DYNAMIC_RELOC
        and SYMBOL_REFERENCES_LOCAL in GOT handling.
