I would call it a bug. I've fixed it like this:

[PATCH] {rand,allyes}packageconfig: ensure legacy test options don't
 get enabled

The legacy BR2_PACKAGE_* options in Config.in.legacy are not supposed to
be user selectable, so {rand,allyes}packageconfig shouldn't enable them.

Looks good, thanks. At least, the autobuilders are a lot happier now :-)

Thanks,

Thomas
