Subject: [PATCH] litecross: build target config logic into the makefile

leaving necessary configuration options for certain targets to the
user is error-prone and inconvenient. instead of configuration for
exact target string matchs in the sample config.mak, provide general
logic in the makefile itself which should cover all variants as well.
