Fixed bogus existence test related to searching for a nearby obj

directory.  config.h is always in the current (= object) directory,
so don't search for it.

config.h is not a source for the library, so don't put it in SRCS and
don't make the library depend on it.

Don't put unused flags in CFLAGS.

Simplify using INTERNALLIB*.
