the
    opt_* file if that is the case, else just create an empty file.
yea, except for the needed source dependancy on the kernel option 
header file, my version does the same (checking for kernel build is 
here simply checking for file existance, though this can be advanced 
somehow). I was hoping for a more terse version than the one below...

maybe i have some idea whilst sleeping

.if !target(opt_blah.h)
.if (some way of determing that we are a kernel build)
opt_blah.h: ${MAKEOBJDIRPREFIX}/opt_blah.h
	install ${.ALLSRC:M*.h} ${.TARGET}
.else

opt_blah.h:
	touch ${.TARGET}
.endif
.endif
