FYI: fix undefined variables warnings in @cond_stack handling

[Alexandre Duret-Lutz]

I'm checking this in.  Warnings were visible with tests/else.test.

2003-07-03  Alexandre Duret-Lutz  <address@hidden>

        * automake.in (cond_stack_else): Return FALSE if `if' was not
        used.
        (cond_stack_endif): Return TRUE if `if' was not used.  Do not
        display $negate and $cond, they are irrelevant and maybe undefined.
