Up to [CENS] / emstar

change to the build system to use configure more for native platform.
also sets up several flags to tell whether the platform has various
special libraries.

also separates out clean and help from the rest so that those don't
go thru dependency generation.

configure automatically runs if you don't run it first for the
native architecture.
