How to test examples / make sure they still build

Clang Frontend
1

Today I ran into a problem after checking in a tested example tool
that the tool is not available when we don't build the examples, thus
the test broke.
I then realized that I also had not added Makefile support for the
example, so I tried to build the examples with autoconf and noticed
they were broken (link failure, Nick submitted a patch).

Now my questions are:
- are tests for examples not supported?
- is there a reason examples are not built in the build bots? (as
everything that's not built tends to rot...)

Cheers,

This is the thread that setted the trend about not building examples by
default on the CMake build (for LLVM, Clang followed suit the same day):

Your report demonstrates that, after all, buildbot maintainers are on
the same boat as newbie users when defaults for build options are
considered :slight_smile:
