Right, people haven't been reading very carefully when updating these
packages, it's fixed in trunk though.

However, when using USE_PKGSRC_GCC_RUNTIME=yes it doesn't matter as
the dependency is explicitly set to gcc47-libs rather than relying on
the result of pmatch (see lang/gcc47-libs/buildlink3.mk).
