Yes, mostly for deambiguating cross compiling and multilib style -m32/-m64.
In addition, I think all LLVM_ENABLE_RUNTIMES projects but openmp switched to lib/$triple/xxx.so for runtime libraries, e.g. libc++.so, libc++abi.so, libunwind.a.
By switching openmp we will improve consistency. Downstream distributions can use the same way to install runtime libraries, instead of doing different things for openmp and non-openmp.
