Refactor ccDynamic for static binaries

ccLibrary uses ccDynamic for linking shared libraries, but bypasses
it by calling directly into ccBase for static libraries.  Instead of
duplicating the same mess for ccBinary, rename ccDynamic to ccLinked
and add the logic for dealing with static or shared linkage.  This
also allows moving the stl logic out of ccBase and into ccLinked.
