[PATCH] Fix a warning message in debug/tst-backtrace4.c

[Tulio Magno Quites Machado Filho]

Modify a warning message so that it doesn't sound as an error, e.g.:
"Obtained backtrace with 6 functions (but wanted at least 6)"

Update a comment too.

	* debug/tst-backtrace4.c (handle_signal): Fix a comment and
	warning message.
