Instead of duplicating the source statements in every architecture just
do it once in the toplevel Kconfig file.

Note that with this the inclusion of arch/$(SRCARCH/Kconfig moves out of
the top-level Kconfig into arch/Kconfig so that don't violate ordering
constraits while keeping a sensible menu structure.

To include kernel/Kconfig.freezer to make sure the dependency between
CONFIG_CGROUP_FREEZER and CONFIG_FREEZER

It will cause building error when I make allmodconfig.

We can use the generic lib to fix these error because the symbol of
libgcc in toolchain is not exported.
