Build option survey for stable/8 r210741 (for nanobsd)

[Poul-Henning Kamp]

I have run the build option survey scripts[1] on stable/8 r210741
and have put the results here:

	http://phk/misc/build_options_stable_8_210741/

This information is particularly useful if you are trying to shoehorn
a NanoBSD image into a small-ish (ie: < 1G by the looks of it) media.

But it also provides a audit of our rarely exercised build options,
and as usual this run does exposes a handful of options that either
do nothing or fail the build.

Those options should probably be reviewed[2]

    It might be worth considering running these scripts on a regular
    basis for -trunk and the active -stable, but be aware that it
    takes half a week on a beefy machine.

[2] Some of the options depend on each other.  The scripts obviously
    are not able to do the full permutational test, but it would be
    nice if it were extended with a list of multiplets that should
    also be tested.
