Expect for "@" when doing "complete break ada" on gdb.ada/complete.exp

  Currently, gdb.ada/complete.exp's "complete break ada" test fails
because the regexp used to match the command's output doesn't expect
"@", but we have an output like:

  ...
  complete break ada
  break ada.assertions.assert
  break ada.calendar.arithmetic.difference
  break ada.calendar.arithmetic_operations.add
  break ada.calendar.arithmetic_operations.add.cold
  break ada.calendar.arithmetic_operations.add@plt
  break ada.calendar.arithmetic_operations.difference
  break ada.calendar.arithmetic_operations.difference@plt
  ...

This patch adds "@" to the regexp, unbreaking the test.

OK?

Hi Sergio,

Thanks for the patch!

I can see this behavior, but only when I link with the shared
version of libgnat. For us at least, on x86_64-linux, this is not
the default. That's probably why I wasn't seeing this.

This is OK.

Ah, I see.  TBH, I haven't investigate this further.  I'm glad you can
reproduce it there.

Thanks, pushed.
