Since set -e is enabled by sys.mk, if the tool cannot be found in PATH then the entire shell command line fails, causing us to not print the error message below and instead silently (due to the @) fail, only getting the usual "Error code 1" print from bmake. Thus, provide a dummy default that will never exist (the same as is used by meta2deps.sh) if which fails so that we get the error message as intended. MFC after: 1 week
