The rationale for changing the default (for cmake and make, I assume
we agree they should have the same default) is that most people
building LLVM don't care about the examples (because they are
developers), and this greatly increases cycle times because of the
sheer number of link steps it adds. Having examples be "optional"
builds for people exploring LLVM seems reasonable to me, the only
value I see in building them regularly is to prevent them from being
out-dated, but I will change (one, fast) buildbot to maintain that.

I will update the doc.
