autoconfig seems completed successfully but you have "libnjni11.so: wrong ELF class: ELFCLASS64 (Possible cause: architecture word width mismatch)" error in the output.

Probably you are executing it with wrong java/jre..
I m talking about the one in $ORACLE_HOME/appsutil. This seems like a architecture(32bit/64bit) related problem.. Ensure you are using the correct java (64 bit).
That may be the cause of it.

But you can also directly check the following MOS note and apply the relevant patch if necessary ->

Why Does Autoconfig Fail On 11.2 Database ORACLE_HOME? (Doc ID 1058815.1)

" 11.2 ORACLE_HOME does not contain 32-bit libraries, but Autoconfig still uses a 32-bit Java version. Therefore the solution is to ensure 64-bit Java is used by applying a Patch." -> 7651166
