fix up gdb.trace

This fixes gdb.trace to be parallel-safe.

2013-11-04  Tom Tromey  <tromey@redhat.com>

	* gdb.trace/mi-traceframe-changed.exp: Pass -DTFILE_DIR
	to compilation.  Use standard_output_file.
	(test_tfind_tfile): Update.
	* gdb.trace/tfile.c (write_basic_trace_file)
	(write_error_trace_file): Use TFILE_DIR.
	* gdb.trace/tfile.exp: Pass -DTFILE_DIR to compilation.  Use
	standard_output_file.
