[gentoo-dev] New global USE flag: qt5

[Michael Palimaka]

Hi all,

Qt 5 has been available for some time, and we are making preparations to 
move it to the tree. As we will be supporting user choice where packages 
can be build against both Qt 4 and Qt 5, we will require a new global 
USE flag:

qt5 - Adds support for the Qt 5 application and UI framework

Please note that this flag will be immediately masked until Qt 5 
actually makes it to the tree, but is required to do the necessary pre-work.

Best regards,
Michael
