[PATCH v3 05/15] ctf test: report.exp

[Yao Qi <yao@codesourcery.com>]

This is a test to see GDB gets the same output as live target and
TFILE trace format.

In V3, we remove the code checking target 'ctf' exists or not, just
issue the command "target ctf report.ctf", if the command is
recognized by GDB, do the tests otherwise, do nothing.

	* gdb.trace/report.exp: Test GDB saves trace data to CTF
	format and read CTF trace file if GDB supports.
