utils/checkpackagelib/lib_mk.py: handle 'else' and 'elif' statements
An 'else' or 'elif' clause inside a make conditional should not be indented in the same way as the if/endif clause. check-package did not recognize the else statement and expected an indentation. For example: ifdef FOOBAR interesting else more interesting endif would, according to check-package, need to become: ifdef FOOBAR interesting else more interesting endif Treat 'else' and 'elif' the same as if-like keywords in the Indent test, but take into account that 'else' is also valid shell, so we need to correctly handle line continuation to prevent complaining about the 'else' in: ifdef FOOBAR if true; \ ... \ else \ ... \ fi endif We don't add the 'else' and 'elif' statements to start_conditional, because it would cause incorrect nesting counting in class OverriddenVariable.
