URL: https://github.com/llvm/llvm-project/commit/a54f160b3a98b91cd241a555d904a6b6453affc4 DIFF: https://github.com/llvm/llvm-project/commit/a54f160b3a98b91cd241a555d904a6b6453affc4.diff LOG: Prefer /usr/bin/env xxx over /usr/bin/xxx where xxx = perl, python, awk Allow users to use a non-system version of perl, python and awk, which is useful in certain package managers.
