commit 750a1c253f81a9dfe2cef5a568c68a5838ab46b9
Author: DJ Delorie <dj@redhat.com>

    [RISC-V] Fix parsing flags in ELF64 files.
    
    When ldconfig reads Elf64 files to determine the ABI, it used the
    Elf32 type, so read the wrong location, and stored the wrong ABI
    type in the cache, making the cache useless.  This patch uses
    an Elf64 type for Elf64 objects instead.
    
    Note that pre-patch caches might need to be manually removed and
    regenerated to get the correct ABIs stored.
    
    	[BZ #22827]
    	* sysdeps/unix/sysv/linux/riscv/readelflib.c (process_elf_file): Use
    	64-bit ELF type for 64-bit ELF objects.
    
    (cherry picked from commit 6a1ff640dcec04905d8518983ad6252d38b7a733)
