In order to prevent this, you have to make sure that each glue driver
depends on USB_ARCH_HAS_EHCI.  A simple way to do this is to surround
the Kconfig entries for those drivers with "if USB && 
USB_ARCH_HAS_EHCI" ... "endif".

I was actually thinking we could remove the use of USB_ARCH_HAS_EHCI
as well once we have inverted the logic for selecting USB_EHCI_HCD,
but there is another problem with that, because then we still need
something to select USB_ARCH_HAS_HCD, or kill that symbol as well.

+1 for killing it. Such symbols get more and more meaningless anyway
with multiarch kernels-
