-B need not be a directory.  -B is a string prefix.  For convenience,
because the -B option is most commonly used with a directory, gcc will
add a trailing '/' when the -B option names a directory.  Otherwise,
since -B is a string prefix, you would have to add the trailing '/'
yourself when using -B.
