[PATCH] Allow gdb version 10 in pretty printer tests.

[Florian Weimer]

* Stefan Liebler via Libc-alpha:

> With gdb 10, the pretty printer tests are UNSUPPORTED::
> The gdb version string (gdb -v) is incorrectly formatted.

> This is observable in:

> nptl/test-rwlock-printers, nptl/test-rwlockattr-printers
>
> After updating the regexp and building with debug-info,
> all those tests are passing.

Looks okay to me, thanks.

I really value your test debugging skills.
