All is broken on 17.5 with HiPE

[kxepal]

Since bear declares a flag to compile with HiPE support, it's surprise that it doesn't works:

I haven't tested bear with newer than R16.

[janl]

does it have to have hipe?

[joewilliams]

If hipe is causing this to be unstable in general I'd be happy to merge a PR removing it.

[kxepal]

@joewilliams I made #23 for that.

Also, we eventually found that erlc provides an option to compile with hipe support +native, but it doesn't gives any options to not do that if some module declares it (except if you build erlang without hipe support). So, I think, in general it's good to delegate decision of compile with native option or not to user`s rebar.config script or whatever is used to build the project.
