package/llvm: remove $ORIGIN/../lib from RPATH
AddLLVM.cmake adds $ORIGIN/../lib to the RPATH of llvm binaries. This causes a problem when llvm-config built for the host, installed in STAGING_DIR, is executed under the following conditions: * Target architecture same as host architecture (normally x86_64) * Target's libc different from host's libc (normally glibc) llvm-config will try to link with the target's libc, resulting in: ./llvm-config: error while loading shared libraries: libc.so.0: cannot open shared object file: No such file or directory. To avoid this, we simply add pass -DCMAKE_INSTALL_RPATH="$(HOST_DIR)/lib" in HOST_LLVM_CONF_OPTS.
