I'm just speculating, but the reason might have been that if you are compiling Linux on some oddball UNIX system, the POSIX shell might not be "/bin/sh", but some other path, who knows which. But if $BASH is defined or if there is /bin/bash, then it's very likely the familiar GNU Bash. Hence the preference. Of course, the side effect is that it makes it easy to introduce bash-only constructs into the scripts :-/.
