Extended Description

The following four commits from master are necessary to fix lldb build on Gentoo which has been broken in 5.0 trunk:

r310712 -- [cmake] Expose the dependencies of ExecutionEngine as PUBLIC
r311122 -- [cmake] Add explicit linkage from Core to curses
r311354 -- [cmake] Explicitly link dependency libraries in the Host library
r311355 -- [unittests] Build LLVMTestingSupport for out-of-source builds

(the first one applies to LLVM, the remaining to LLDB)
