litecross: fix $(TARGET)-based config when value comes from config.mak

commit 03bd65562a509ff86bfe8861f8e51e973bcfdd3b wrongly placed the
logic conditional on $(TARGET) before inclusion of config.mak, so that
it only worked when TARGET was set from the make command line or
environment. reorder to fix.
