…db-resource-headers
The Xcode build otherwise fails with
```
CMake Error in source/API/CMakeLists.txt:
The custom command generating
/Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake-standalone/lldb-xcode-build/include/lldb/API/SBLanguages.h
is attached to multiple targets:
lldb-sbapi-dwarf-enums
liblldb-resource-headers
but none of these is a common dependency of the other(s). This is not
allowed by the Xcode "new build system".
CMake Generate step failed. Build files cannot be regenerated correctly.
