update/release: disable status checking

just to ensure that nothing goes wrong. we don't rely on
the status variable for releases, because there is another
variable, release, that target.cfg files declare, e.g.

release="n"
release="y"

you can just omit the variable, because it defaults to y, so
you only need declare it when it needs to be "n"
