    gcore: fix memory allocation failure during processing NT_AUXV note

    For crash dumps generated using kernel-4.18.0-365.el8 or later on
    CentOS stream 8, crash gcore command fails as follows:

        crash> gcore -v 7 -f 128 10604
        gcore: Opening file core.10604.test-dumpfilter ...
        gcore: done.
        gcore: Writing ELF header ...
        gcore:  done.
        gcore: Retrieving and writing note information ...
        gcore: zero-size memory allocation! (called from 7fd558ce1e05)
        Failed.

    This memory allocation failure occurs in fill_auxv_note() that creates
    NT_AUXV note due to saved_auxv entries of size and offset tables are
    somehow 0.

    This is because during the merge of the upstream kernel commit
    1c33bb0507508af24fd754dd7123bd8e997fab2f (x86/elf: Support a new ELF
    aux vector AT_MINSIGSTKSZ), location of saved_auxv of struct mm_struct
    has been moved as workaround in order to avoid kABI breakage.

    Fix this by using RHEL-specific location for saved_auxv if there is
    member rh_reserved_saved_auxv in struct mm_struct.
