[cfe-dev] clang/llvm cmake static build broken on Linux

[Vince Harron]

The first checkin with support for LLVM_BUILD_STATIC has this linking
error, so the flag just isn't intended do what I expected.  I am able to
build lldb-platform/lldb-gdbserver statically with this flag so it's
working for me.
