qt5-mac @5.3.1_0 : enable parallel builds

[mkae (Marko Käning)]

Herewith I can verify that qt5-mac builds fine on Mavericks 10.9.3.

So, we can consider removing "use_parallel_build no" once the other OSX versions acknowledge this as well.

OK, I want to add that I was also able to build qt5-creator-mac in parallel without any trouble.

The question is whether we'd need to wait for the other OSX versions, or can simply conclude from Mavericks' successful build that it can be switched on in general?

Replying to mk@…:

Be careful there. Building in parallel on your machine doesn't guarantee that it works on others. For example, take a look at #28878 and #23531. That being said, I think those issues are old and probably due to gcc-4.2. I would be in favor of setting parallel building for both qt5 and also for boost.

[KubaO (Kuba Ober)]

Both Qt5 and Qt creator are supporting parallel builds and this doesn't need any testing/verification. The entire Qt continuous integration system has been parallel building since day 1 IIRC, and they consider broken parallel builds to be serious issues. There's no reason to have parallel building disabled. Really.

mcalhoun, do you have objections? Since this port is openmaintainer, I could commit the change myself, but given the effort you've invested I think you might want to be the one who decides that.
