QNX: Fix detection of QCC compiler id (#15349)
In commit v3.1.0-rc1~113^2 (Use a more reliable regex for extracting
binary INFO strings, 2014-09-03) the matching of INFO: strings was made
more strict and no longer matches just "INFO:qnxnto".  Use
"INFO:qnxnto[]" instead to conform to the new pattern.
