Is it guaranteed that make will always under all circumstances run the
shell with the "-e" flag? And if it does, does GNU make from the ports
do that as well? The '&&' variant will do The Right Thing® with and
without the -e flag passed down the /bin/sh, whereas a 'cd /nonexistent ;
rm -rf * .??*' will happily erase the current working directory if
/nonexistent is non-existent and the shell is run without -e.
