[Development] iOS, libpcre16, QString::trimmed_helper()

[Harri Pasanen]

I'm attempting to use libQt5Core with self compiled qt5.5 snapshot, 
which is a couple of weeks old.   The link fails, complaining about 
missing libpcre16.
I believe that is not standard on iOS, at least it does not come up when 
looking for "Other Libs" pcre in XCode.   There does seem to be some 
version of libpcre for OSX.

Trying with Qt5.4, I have another error, where 
QString::trimmed_helper(QString const &) is missing.

Any advice?
