Any objections to swapping base compilers to make gcc4.7 the default?

[Justin Sherrill]

The only thing I can think of: can you quantify which packages aren't
building?  It sounds like this will break some packages, at least
temporarily, but I don't know which.

The ideal scenario is to never have anyone need to/care to put
DRAGONFLY_CCVER into their mk.conf.  That might be likely if the packages
affected are old enough/rarely used enough.
