[PATCH] uml: add debug switch for skas mode
It doesn't do anything but emit a warning, but there's a user population
that's used to adding 'debug' to the UML command line in order to gdb it.
With skas0 mode, that's not necessary, but these users need some indication
that 'debug' doesn't do what they want.
