Disable relocations when linking with LLD
Is there an option for lld that will tell it not to perform relocations. I don't want PIC code, I just want relocations not to be performed. (Yes I know this will result in an executable that doesn't work.)

Android llvm linker
I heard the Android llvm toolchain use mclinker. But the llvm default linker is lld during its early development stage. Anyone know if it will use lld when lld is mature or plan to keep going with mclinker and enhance mclinker in future.
