I saw this on PPC64 once:

You can't do that when your target is `native'
(gdb) FAIL: gdb.trace/actions.exp: tstart

followed by a cascade of FAILs. The "tstatus" was supposed to detect
that this target (native) can't do tracepoints, but, alas, it didn't.
That detection failed because 'gdb_test "break main"' doesn't expect
anything, and then the output was slow enough that 'gdb_test ""
"Breakpoint .*"' matched the output of "break main"...
The fix is to use gdb_breakpoint instead. Also check the result of
gdb_test while at it.
Tested on x86-64 Fedora 20, native and gdbserver.
gdb/testsuite/ChangeLog:

* gdb.trace/actions.exp: Use gdb_breakpoint instead of gdb_test
that doesn't expect anything. Return early if running to main
fails.
