m68k: default value for MEMORY_RESERVE?

Hi Geert,

Would it be safe (or unsafe) to add a default value for MEMORY_RESERVE?

As it is, kconfig can generate a randconfig with
"CONFIG_MEMORY_RESERVE=" (no value) since it has no default.

Then a following 'make all' finds an invalid symbol value and restarts
the config:

.config:214:warning: symbol value '' invalid for MEMORY_RESERVE
* Restart config...
Memory reservation (MiB) (MEMORY_RESERVE) [] (NEW)

That's OK until I try to script/automate randconfig builds.

Can we do anything about this or should I just add it to my
