We cannot depend on the x bit.  Because downloading linux-foo.patch.gz
and installing it with patch(1) is a supported way of obtaining Linux. 
And patch(1) loses the x bit.

If $(CONFIG_SHELL) is unavailable then invoking the script with
"/bin/sh foo.sh" should do the trick.

So all confused.  I'll drop this version - please redo and resend when
convenient?
