    [gdb/testsuite] Fix gdb.base/ending-run.exp on manjaro linux
    
    On aarch64-linux, using the manjaro linux distro, I run into:
    ...
    (gdb) next^M
    32      }^M
    (gdb) next^M
    0x0000fffff7d67b80 in ?? () from /usr/lib/libc.so.6^M
    (gdb) FAIL: gdb.base/ending-run.exp: step out of main
    ...
    
    What happens here is described in detail in this clause:
    ...
        -re "0x.*\\?\\? \\(\\) from /lib/powerpc.*$gdb_prompt $" {
            # This case occurs on Powerpc when gdb steps out of main and the
            # needed debug info files are not loaded on the system, preventing
            # GDB to determine which function it reached (__libc_start_call_main).
            # Ideally, the target system would have the necessary debugging
            # information, but in its absence, GDB's behavior is as expected.
            ...
        }
    ...
    but the clause only matches for powerpc.
    
    Fix this by:
    - making the regexp generic enough to also match /usr/lib/libc.so.6, and
    - updating the comment to not mention powerpc.
    
    Tested on aarch64-linux.
