[PATCH 4/4] ld: Fix discarded-qualifiers problems in ldelf.c

[Calvin Owens]

    ../../ld/ldelf.c: In function ‘ldelf_search_needed’:
    ../../ld/ldelf.c:538:34: error: assignment discards ‘const’ qualifier from pointer target type [-Werror=discarded-qualifiers]
      538 |                       if ((slash = strrchr (replacement, '/')) != NULL)
          |                                  ^

Fix this by passing the obviously equal non-const pointer to strrchr(),
instead of the const one.

    ../../ld/ldelf.c: In function ‘ldelf_parse_ld_so_conf_include’:
    ../../ld/ldelf.c:797:17: error: initialization discards ‘const’ qualifier from pointer target type [-Werror=discarded-qualifiers]
      797 |       char *p = strrchr (filename, '/');
          |                 ^~~~~~~

Fix this by declaring the local pointer varaible as const, since it is
not modified.
