c++11

[Thomas Klausner <tk%giga.or.at@localhost>]

Hi!

Currently, when a package needs C++11, we set

CXXFLAGS+= -std=c++11

and hope for the best, i.e. that the platform compiler supports this.

Shouldn't we rather add support to USE_LANGUAGES like this:

USE_LANGUAGES+=	c++11

and make bsd.pkg.mk set CXXFLAGS and request a good-enough compiler?
