* add ${GCCARCH} to .PATH to make hconfig.h a real file target. 

* use ${G_HCONFIG_H} instead of hconfig.h as a dependency.
* hconfig.h: auto-build.h dependency is bogus, remove.
* misc cleanup of ".c depends on .h" -> ".o depends on .h"
* options.h was missing from CLEANFILES.

With these changes running make in this directory doesn't do a
*complete* rebuild anymore.  Still not foolproof, because gen* host
tools do not overwrite generated files that are not changed, so we
really need to use stamp file style dependencies for those, like gcc
makefile does.

Ok by Matthew Green <mrg@netbsd>.
