    [gdb/testsuite] Fix test-case gdb.threads/attach-stopped.exp on manjaro
linux

    When running test-case gdb.threads/attach-stopped.exp on aarch64-linux,
using
    the manjaro linux distro, I get:
    ...
     (gdb) thread apply all bt^M
     ^M
     Thread 2 (Thread 0xffff8d8af120 (LWP 278116) "attach-stopped"):^M

     #2  0x0000ffff8d969b68 in sleep () from /usr/lib/libc.so.6^M

     #5  0x0000ffff8d99a5dc in ?? () from /usr/lib/libc.so.6^M
     ^M
     Thread 1 (Thread 0xffff8db62020 (LWP 278111) "attach-stopped"):^M
     #0  0x0000ffff8d92d2d8 in ?? () from /usr/lib/libc.so.6^M
     #1  0x0000ffff8d9324b8 in ?? () from /usr/lib/libc.so.6^M
     #2  0x0000aaaade37086c in main () at attach-stopped.c:45^M
     (gdb) FAIL: gdb.threads/attach-stopped.exp: threaded: attach2 to stopped
bt
    ...

    The problem is that the test-case expects to see start_thread:
    ...
            gdb_test "thread apply all bt" ".*sleep.*start_thread.*" \
                "$threadtype: attach2 to stopped bt"
    ...
    but lack of symbols makes that impossible.

    Fix this by allowing " in ?? () from " as well.

    Tested on aarch64-linux.
