That is not the problem. Since in cases of target its finding is properly. there are multiple pieces where some are being built for native( build host) some for target so it thinks its building for buildhost (native) llvm-config e.g. is one such case. Replacing it with -lz fixes it becasue compile environment is providing right --sysroot for native or cross cases and it always links with correct libs.
