FALSE is used as a key in %{conditions}{$var} for instance, or when
dumping the variable.  `#' is used when outputting the Makefile.

For some time I thought it might be useful to see what would have
happened with FALSE conditions (in the sense of variable_dump).  But
ISTR I hit a limitation (something like multiple definition under the
same condition: FALSE) which made it impossible.

It is probably safer now to make it a prog_error to macro_define under
FALSE.
