ld: -bundle and -bitcode_bundle cannot be used together

问题

i'm building llvm/clang 3.7 with bitcode support (-fembed-bitcode). Some modules can't be linked due to error:

ld: -bundle and -bitcode_bundle (Xcode setting ENABLE_BITCODE=YES) cannot be used together clang: error: linker command failed with exit code 1 (use -v to see invocation)

Full error output:

It seems that -bundle is added by CMake as i was not able to find it in CMakeLists.txt and -bitcode_bundle is added by SDK because of -fembed-bitcode.

How can i fix it? Any workaround (f.e. to switch off dylibs building since i don't need them)?
