you probably want to keep ${BUILT_PRODUCTS_DIR} at the front -- you don't know
what the pwd is when this file is executed

To make the line shorter:
SRCROOT="${BUILT_PRODUCTS_DIR}/../.."
CLANGVER=$(python ${SRCROOT}/tools/clang/scripts/update.py
--print-clang-version)
ASAN_DYLIB=${SRCROOT}/third_party/llvm-build/Release+Asserts/lib/clang/${CLANGVER}/lib/darwin/${ASAN_DYLIB_NAME}
