In XSL a string variable can be nul, the empty string or a non-empty string. While `$var != ''` ensures that `var` is a non-empty string, `$var = ''` is true only when `var` holds the empty string. In other words, `$var = ''` and `$var != ''` can be both false if `var` evaluates to nul. As a result, the config.h/config.mk generating scripts does not use the given default value if the explicit value is nul. This patch fixes the incorrect comparison in the XSL scripts that handles default values, so that the default value behaves as expected.
