Convert databases/evolution-data-server to USES=compiler:c++11-lib
so that on FreeBSD 8 and 9 it will be linked to the newer libstdc++
bundled with lang/gcc. This unbreaks the startup of mail/evolution
on FreeBSD 8 and 9 because evolution is also linked to webkit-gtk3,
which requires the newer libstdc++ and causes rtld to fail if the
base version of libstdc++ has already been loaded.
