Unbuffer all tests that rely on stdio This forces all tests that rely on stdio to be unbuffered, like interrupt.exp was adjusted in 6f98576f. To recap, in some scenarios, GDB or GDBserver can be spawned with input _not_ connected to a tty, and then tests that rely on stdio fail with timeouts, because the inferior's stdout and stderr streams end up fully buffered. Calling gdb_unbuffer_output forces output to be unbuffered. See https://sourceware.org/ml/gdb-patches/2015-02/msg00809.html and https://sourceware.org/ml/gdb-patches/2015-02/msg00819.html. Tested on x86_64 Fedora 20, native, and against a remote gdbserver board file that connects to the target with ssh, with and without -t (create pty). gdb/testsuite/ChangeLog: 2015-07-29 Pedro Alves <palves@redhat.com> * gdb.base/call-ar-st.c: Include "../lib/unbuffer_output.c".
