It is possible to select an m68k MMU build but not actually enable any
of the three MMU options, which then results in a build failure:
arch/m68k/include/asm/page.h:10:25: error: 'CONFIG_PAGE_SHIFT' undeclared here (not in a function); did you mean 'CONFIG_LOG_BUF_SHIFT'?
Change the Kconfig selection to ensure that exactly one of the three
options is always enabled whenever an MMU-enabled kernel is built, but
moving CONFIG_SUN3 into a top-level option next to M68KCLASSIC and
COLDFIRE.
All defconfig files should keep working without changes, but
alldefconfig now builds support for the classic MMU.
