I understand the idea, but we need to realize it has some drawbacks:

 - If we add additional flags for some architecture, this will have to
   be updated.

 - If some custom flags are passed in BR2_TARGET_OPTIMIZATION, I would
   assume it would also cause a build failure, no ?

If we really can't remove the package, then I'm fine with this patch as
a stop-gap measure. But I think removing the package is the sanest
thing to do. If anything, removing the package might wake up the people
using it so that they fix it.
