interdependencies

Partial fix as described in description
lldb fails to build with "undefined reference to ......" errors because its
various libraries use each other's symbols without linking to each other.
I have a patch that starts fixing it by using target_link_libraries where the
dependencies are clear -- but it ends up still not building because of circular
dependencies (lldbCore uses symbols from lldbSymbols and friends while
lldbSymbols etc. rely on lldbCore at the same time).
(This is a 4.0 snapshot from yesterday, building with a current clang 4.0
snapshot on Linux -- 4.0/master doesn't show up in the list of possible
versions)
