This configuration exercises various --disable-* configure options.
It is expected to catch -Werror failures that only affect these
configurations.

There is a --disable-tunables too which works the same and looks 
prettier in that context ;)

The INSTALL lists --disable-scv and --disable-experimental-malloc too. 
As an aside, maybe we should graduate tcache from being 'experimental' 
to being more permanent in 2.35 and then make this option nop.

It's not documented, but I can use it still.

--disable-scv isn't about minimization.  I forgot that
--disable-experimental-malloc controls tcache.

I'm going to send an updated patch.
