rules.mk: make toolchain dirs define more consistent

Make toolchain dirs define more consistent between internal and external
toolchains.

Make use of specific dirs also for intenral toolchain and generilize
include and lib inclusion.

Also set TOOLCHAIN_ROOT_DIR for internal toolchain as this is what
packages should use to reference staging toolchain directory.
