x86: fix up alternatives with lockdep enabled

Browse Source 
An older binutils bug caused us to not fix up alternatives.
This problem involved mutex.c but we dont do lockdep section tricks
there anymore, so this workaround is moot. Keep the printk nevertheless,
just in case ... We can remove that later on.
