menuconfig and mrproper are frequently used operations during a new
architecture porting, testing or debugging.

menuconfig is required to tune and test extra kernel config options for
tinyconfig.

mrproper is required to get a clean srctree while want to start a new
building with O= option, the old generated files in srctree must be
mrproper-ed.

differ from local nolibc targets, the menuconfig and mrproper targets
from top-level Makefile accept different ARCH variable and require extra
'-C /path/to/srctree', which make development not consistent and
therefore very painful, let's add local menuconfig and mrproper targets
too.

To reduce duplicated entries, menuconfig and mrproper are added
together.
